Persepolis Founded by Darius I in 518 B.C., Persepolis was the capital of the Achaemenid Empire. It was built on an immense half-artificial, half-natural terrace, where the king of kings created an impressive palace complex inspired by Mesopotamian models. The importance and quality of the monumental ruins make it a unique archaeological site.

Persepolis, whose magnificent ruins rest at the foot of Kuh-e Rahmat (Mountain of Mercy) in south-western Iran, is among the world’s greatest archaeological sites. Renowned as the gem of Achaemenid (Persian) ensembles in the fields of architecture, urban planning, construction technology, and art, the royal city of Persepolis ranks among the archaeological sites which have no equivalent and which bear unique witness to a most ancient civilization. The city’s immense terrace was begun about 518 BCE by Darius the Great, the Achaemenid Empire’s king. On this terrace, successive kings erected a series of architecturally stunning palatial buildings, among them the massive Apadana palace and the Throne Hall (“Hundred-Column Hall”).

Inspired by Mesopotamian models, the Achaemenid kings Darius I (522-486 BCE), his son Xerxes I (486-465 BCE), and his grandson Artaxerxes I (465-424 BCE) built a splendid palatial complex on an immense half-natural, half-artificial terrace. This 13-ha ensemble of majestic approaches, monumental stairways, throne rooms (Apadana), reception rooms, and dependencies is classified among the world’s greatest archaeological sites. The terrace is a grandiose architectural creation, with its double flight of access stairs, walls covered by sculpted friezes at various levels, contingent Assyrianesque propylaea (monumental gateway), gigantic sculpted winged bulls, and remains of large halls. By carefully engineering lighter roofs and using wooden lintels, the Achaemenid architects were able to use a minimal number of astonishingly slender columns to support open area roofs. Columns were topped with elaborate capitals; typical was the double-bull capital where, resting on double volutes, the forequarters of two kneeling bulls, placed back-to-back, extend their coupled necks and their twin heads directly under the intersections of the beams of the ceiling.

The Meidan Emam is a public urban square in the centre of Esfahan, a city located on the main north-south and east-west routes crossing central Iran. It is one of the largest city squares in the world and an outstanding example of Iranian and Islamic architecture. Built by the Safavid shah Abbas I in the early 17th century, the square is bordered by two-storey arcades and anchored on each side by four magnificent buildings: to the east, the Sheikh Lotfallah Mosque; to the west, the pavilion of Ali Qapu; to the north, the portico of Qeyssariyeh; and to the south, the celebrated Royal Mosque. A homogenous urban ensemble built according to a unique, coherent, and harmonious plan, the Meidan Emam was the heart of the Safavid capital and is an exceptional urban realisation.

Also known as Naghsh-e Jahan (“Image of the World”), and formerly as Meidan-e Shah, Meidan Emam is not typical of urban ensembles in Iran, where cities are usually tightly laid out without sizeable open spaces. Esfahan’s public square, by contrast, is immense: 560 m long by 160 m wide, it covers almost 9 ha. All of the architectural elements that delineate the square, including its arcades of shops, are aesthetically remarkable, adorned with a profusion of enamelled ceramic tiles and paintings.

Of particular interest is the Royal Mosque (Masjed-e Shah), located on the south side of the square and angled to face Mecca. It remains the most celebrated example of the colourful architecture which reached its high point in Iran under the Safavid dynasty (1501-1722; 1729-1736). The pavilion of Ali Qapu on the west side forms the monumental entrance to the palatial zone and to the royal gardens which extend behind it. Its apartments, high portal, and covered terrace (tâlâr) are renowned. The portico of Qeyssariyeh on the north side leads to the 2-km-long Esfahan Bazaar, and the Sheikh Lotfallah Mosque on the east side, built as a private mosque for the royal court, is today considered one of the masterpieces of Safavid architecture.

The Meidan Emam was at the heart of the Safavid capital’s culture, economy, religion, social power, government, and politics. Its vast sandy esplanade was used for celebrations, promenades, and public executions, for playing polo and for assembling troops. The arcades on all sides of the square housed hundreds of shops; above the portico to the large Qeyssariyeh bazaar a balcony accommodated musicians giving public concerts; the tâlâr of Ali Qapu was connected from behind to the throne room, where the shah occasionally received ambassadors. In short, the royal square of Esfahan was the preeminent monument of Persian socio-cultural life during the Safavid dynasty.

Pasargadae was the first dynastic capital of the Achaemenid Empire, founded by Cyrus II the Great, in Pars, homeland of the Persians, in the 6th century BC. Its palaces, gardens and the mausoleum of Cyrus are outstanding examples of the first phase of royal Achaemenid art and architecture and exceptional testimonies of Persian civilization. Particularly noteworthy vestiges in the 160-ha site include: the Mausoleum of Cyrus II; Tall-e Takht, a fortified terrace; and a royal ensemble of gatehouse, audience hall, residential palace and gardens. Pasargadae was the capital of the first great multicultural empire in Western Asia. Spanning the Eastern Mediterranean and Egypt to the Hindus River, it is considered to be the first empire that respected the cultural diversity of its different peoples. This was reflected in Achaemenid architecture, a synthetic representation of different cultures. 

Bam is situated in a desert environment on the southern edge of the Iranian high plateau. The origins of Bam can be traced back to the Achaemenid period (6th to 4th centuries BC). Its heyday was from the 7th to 11th centuries, being at the crossroads of important trade routes and known for the production of silk and cotton garments. The existence of life in the oasis was based on the underground irrigation canals, the qanāts, of which Bam has preserved some of the earliest evidence in Iran. Arg-e Bam is the most representative example of a fortified medieval town built in vernacular technique using mud layers (Chineh ).

The archaeological site of Takht-e Soleyman, in north-western Iran, is situated in a valley set in a volcanic mountain region. The site includes the principal Zoroastrian sanctuary partly rebuilt in the Ilkhanid (Mongol) period (13th century) as well as a temple of the Sasanian period (6th and 7th centuries) dedicated to Anahita. The site has important symbolic significance. The designs of the fire temple, the palace and the general layout have strongly influenced the development of Islamic architecture.

Tchogha Zanbil – The ruins of the holy city of the Kingdom of Elam, surrounded by three huge concentric walls, are found at Tchogha Zanbil. Founded c. 1250 B.C., the city remained unfinished after it was invaded by Ashurbanipal, as shown by the thousands of unused bricks left at the site.

The mausoleum of Oljaytu was constructed in 1302–12 in the city of Soltaniyeh, the capital of the Ilkhanid dynasty, which was founded by the Mongols. Situated in the province of Zanjan, Soltaniyeh is one of the outstanding examples of the achievements of Persian architecture and a key monument in the development of its Islamic architecture. The octagonal building is crowned with a 50 m tall dome covered in turquoise-blue faience and surrounded by eight slender minarets. It is the earliest existing example of the double-shelled dome in Iran. The mausoleum’s interior decoration is also outstanding and scholars such as A.U. Pope have described the building as ‘anticipating the Taj Mahal’.

Bisotun is located along the ancient trade route linking the Iranian high plateau with Mesopotamia and features remains from the prehistoric times to the Median, Achaemenid, Sassanian, and Ilkhanid periods. The principal monument of this archaeological site is the bas-relief and cuneiform inscription ordered by Darius I, The Great, when he rose to the throne of the Persian Empire, 521 BC. The bas-relief portrays Darius holding a bow, as a sign of sovereignty, and treading on the chest of a figure who lies on his back before him. According to legend, the figure represents Gaumata, the Median Magus and pretender to the throne whose assassination led to Darius’s rise to power. Below and around the bas-reliefs, there are ca. 1,200 lines of inscriptions telling the story of the battles Darius waged in 521-520 BC against the governors who attempted to take apart the Empire founded by Cyrus. The inscription is written in three languages. The oldest is an Elamite text referring to legends describing the king and the rebellions. This is followed by a Babylonian version of similar legends. The last phase of the inscription is particularly important, as it is here that Darius introduced for the first time the Old Persian version of his res gestae (things done). This is the only known monumental text of the Achaemenids to document the re-establishment of the Empire by Darius I. It also bears witness to the interchange of influences in the development of monumental art and writing in the region of the Persian Empire. There are also remains from the Median period (8th to 7th centuries B.C.) as well as from the Achaemenid (6th to 4th centuries B.C.) and post-Achaemenid periods.

Located in the historic center of Isfahan, the Masjed-e Jāmé (‘Friday mosque’) can be seen as a stunning illustration of the evolution of mosque architecture over twelve centuries, starting in ad 841. It is the oldest preserved edifice of its type in Iran and a prototype for later mosque designs throughout Central Asia. The complex, covering more than 20,000 m², is also the first Islamic building that adapted the four-courtyard layout of Sassanid palaces to Islamic religious architecture. Its double-shelled ribbed domes represent an architectural innovation that inspired builders throughout the region. The site also features remarkable decorative details representative of stylistic developments over more than a thousand years of Islamic art.

The City of Yazd is located in the middle of the Iranian plateau, 270 km southeast of Isfahan, close to the Spice and Silk Roads. It bears living testimony to the use of limited resources for survival in the desert. Water is supplied to the city through a qanat system developed to draw underground water. The earthen architecture of Yazd has escaped the modernization that destroyed many traditional earthen towns, retaining its traditional districts, the qanat system, traditional houses, bazars, hammams, mosques, synagogues, Zoroastrian temples and the historic garden of Dolat-abad. 

The lavish Golestan Palace is a masterpiece of the Qajar era, embodying the successful integration of earlier Persian crafts and architecture with Western influences. The walled Palace, one of the oldest groups of buildings in Teheran, became the seat of government of the Qajar family, which came into power in 1779 and made Teheran the capital of the country. Built around a garden featuring pools as well as planted areas, the Palace’s most characteristic features and rich ornaments date from the 19th century. It became a centre of Qajari arts and architecture of which it is an outstanding example and has remained a source of inspiration for Iranian artists and architects to this day. It represents a new style incorporating traditional Persian arts and crafts and elements of 18th century architecture and technology.

The Armenian Monastic Ensembles of Iran, in the north-west of the country, consists of three monastic ensembles of the Armenian Christian faith: St Thaddeus and St Stepanos and the Chapel of Dzordzor. These edifices – the oldest of which, St Thaddeus, dates back to the 7th century – are examples of outstanding universal value of the Armenian architectural and decorative traditions. They bear testimony to very important interchanges with the other regional cultures, in particular the Byzantine, Orthodox and Persian. Situated on the south-eastern fringe of the main zone of the Armenian cultural space, the monasteries constituted a major centre for the dissemination of that culture in the region. They are the last regional remains of this culture that are still in a satisfactory state of integrity and authenticity. Furthermore, as places of pilgrimage, the monastic ensembles are living witnesses of Armenian religious traditions through the centuries.

Gonbad-e Qābus: 
The 53 m high tomb built in ad 1006 for Qābus Ibn Voshmgir, Ziyarid ruler and literati, near the ruins of the ancient city of Jorjan in north-east Iran, bears testimony to the cultural exchange between Central Asian nomads and the ancient civilization of Iran. The tower is the only remaining evidence of Jorjan, a former centre of arts and science that was destroyed during the Mongols’ invasion in the 14th and 15th centuries. It is an outstanding and technologically innovative example of Islamic architecture that influenced sacral building in Iran, Anatolia and Central Asia. Built of unglazed fired bricks, the monument’s intricate geometric forms constitute a tapering cylinder with a diameter of 17–15.5 m, topped by a conical brick roof. It illustrates the development of mathematics and science in the Muslim world at the turn of the first millennium AD.

Cultural Landscape of Maymand:

Maymand is a self-contained, semi-arid area at the end of a valley at the southern extremity of Iran’s central mountains. The villagers are semi-nomadic agro-pastoralists. They raise their animals on mountain pastures, living in temporary settlements in spring and autumn. During the winter months they live lower down the valley in cave dwellings carved out of the soft rock (kamar), an unusual form of housing in a dry, desert environment.  This cultural landscape is an example of a system that appears to have been more widespread in the past and involves the movement of people rather than animals.

Sassanid Archaeological Landscape of Fars Region:

The eight archaeological sites situated in three geographical areas in the southeast of Fars Province: Firuzabad, Bishapur and Sarvestan. The fortified structures, palaces and city plans date back to the earliest and latest times of the Sassanian Empire, which stretched across the region from 224 to 658 CE. Among these sites is the capital built by the founder of the dynasty, Ardashir Papakan, as well as a city and architectural structures of his successor, Shapur I. The archaeological landscape reflects the optimized utilization of natural topography and bears witness to the influence of Achaemenid and Parthian cultural traditions and of Roman art, which had a significant impact on the architecture of the Islamic era.

Shahr-i Sokhta, meaning ‘Burnt City’, is located at the junction of Bronze Age trade routes crossing the Iranian plateau. The remains of the mudbrick city represent the emergence of the first complex societies in eastern Iran. Founded around 3200 BC, it was populated during four main periods up to 1800 BC, during which time there developed several distinct areas within the city: those where monuments were built, and separate quarters for housing, burial and manufacture. Diversions in water courses and climate change led to the eventual abandonment of the city in the early second millennium. The structures, burial grounds and large number of significant artefacts unearthed there, and their well-preserved state due to the dry desert climate, make this site a rich source of information regarding the emergence of complex societies and contacts between them in the third millennium BC.

Sheikh Safi al-din Khānegāh and Shrine Ensemble in Ardabil

Built between the beginning of the 16^th century and the end of the 18^th century, this place of spiritual retreat in the Sufi tradition uses Iranian traditional architectural forms to maximize use of available space to accommodate a variety of functions (including a library, a mosque, a school, mausolea, a cistern, a hospital, kitchens, a bakery, and some offices). It incorporates a route to reach the shrine of the Sheikh divided into seven segments, which mirror the seven stages of Sufi mysticism, separated by eight gates, which represent the eight attitudes of Sufism. The ensemble includes well-preserved and richly ornamented facades and interiors, with a remarkable collection of antique artefacts. It constitutes a rare ensemble of elements of medieval Islamic architecture.

Shushtar Historical Hydraulic System:

Shushtar, Historical Hydraulic System, inscribed as a masterpiece of creative genius, can be traced back to Darius the Great in the 5th century B.C. It involved the creation of two main diversion canals on the river Kârun one of which, Gargar canal, is still in use providing water to the city of Shushtar via a series of tunnels that supply water to mills. It forms a spectacular cliff from which water cascades into a downstream basin. It then enters the plain situated south of the city where it has enabled the planting of orchards and farming over an area of 40,000 ha. known as Mianâb (Paradise). The property has an ensemble of remarkable sites including the Salâsel Castel, the operation centre of the entire hydraulic system, the tower where the water level is measured, dams, bridges, basins and mills. It bears witness to the know-how of the Elamites and Mesopotamians as well as more recent Nabatean expertise and Roman building influence.
