Iranian architecture or Persian architecture is the architecture of Iran that has a continuous history from at least 5000 BCE to the present, with characteristic examples distributed over a vast area from Turkey to North India and the borders of China, from the Caucasus to Zanzibar. Persian buildings vary from peasant huts to tea houses, and garden pavilions to "some of the most majestic structures the world has ever seen".
Iranian architecture displays great variety, both structural and aesthetic, developing gradually and coherently out of prior traditions and experience. Without sudden innovations, and despite the repeated trauma of invasions and cultural shocks, it has achieved "an individuality distinct from that of other Muslim countries"] Its paramount virtues are several: "a marked feeling for form and scale; structural inventiveness, especially in vault and dome construction; a genius for decoration with a freedom and success not rivaled in any other architecture".
Traditionally, the guiding, formative, motif of Iranian architecture has been its cosmic symbolism "by which man is brought into communication and participation with the powers of heaven". This theme, shared by virtually all Asia and persisting even into modern times, not only has given unity and continuity to the architecture of Persia, but has been a primary source of its emotional characters as well.
Fundamental principlesTraditional Persian architecture has maintained a continuity that, although temporarily diverted by political internal conflicts or foreign intrusion, nonetheless has achieved a style that could hardly be mistaken for any other.
In this architecture, "there are no trivial buildings; even garden pavilions have nobility and dignity, and the humblest caravanserais generally have charm. In expressiveness and communicativity, most Persian buildings are lucid - even eloquent. The combination of intensity and simplicity of form provides immediacy, while ornament and, often, subtle proportions reward sustained observation."
Categorization of styles
Overall, the traditional architecture of the Iranian lands throughout the ages can be categorized into the six following classes or styles ("sabk"):
- Pre-Islamic:
- The Parsian style (Achaemenid, Median, Elamite eras)
- The Parthian style (Parthian, Sassanid eras)
- Islamic:
- The Khorasani style
- The Razi style
- The Azari style
- The Isfahani style
Materials
Available building materials dictate major forms in traditional Iranian architecture. Heavy clays, readily available at various places throughout the plateau, have encouraged the development of the most primitive of all building techniques, molded mud, compressed as solidly as possible, and allowed to dry. This technique used in Iran from ancient times has never been completely abandoned. The abundance of heavy plastic earth, in conjunction with a tenacious lime mortar, also facilitated the development of the brick.
Geometry
Iranian architecture makes use of abundant symbolic geometry, using pure forms such as the circle and square, and plans are based on often symmetrical layouts featuring rectangular courtyards and halls.
Design
Certain design elements of Persian architecture have persisted throughout the history of Iran. The most striking are a marked feeling for scale and a discerning use of simple and massive forms. The consistency of decorative preferences, the high-arched portal set within a recess, columns with bracket capitals, and recurrent types of plan and elevation can also be mentioned. Through the ages, these elements have recurred in completely different types of buildings constructed for various programs and under the patronage of a long succession of rulers.
The columned porch, or talar, seen in the rock-cut tombs near Persepolis, reappear in Sassanid temples, and in late Islamic times it was used as the portico of a palace or mosque, and adapted even to the architecture of roadside tea-houses. Similarly, the gonbad on four arches, so characteristic of Sassanid times, is a still to be found in many cemeteries and Imamzadehs across Iran today. The notion of earthly towers reaching up toward the sky to mingle with the divine towers of heaven lasted through the 19th century, while the interior court and pool, the angled entrance and extensive decoration are ancient but still common features of Iranian architecture.
Pre-Islamic architecture of Persia
- Main articles: Achaemenid architecture & Sassanid architecture
The pre-Islamic styles draw on 3-4 thousand years of architectural development from various civilizations of the Iranian plateau. The post-Islamic architecture of Iran in turn, draws ideas from its pre-Islamic predecessor, and has geometrical and repetitive forms, as well as surfaces that are richly decorated with glazed tiles, carved stucco, patterned brickwork, floral motifs, and calligraphy.
As such, Iran ranks seventh in the world in terms of possessing historical monuments, museums, and other cultural attractions and is recognized by UNESCO as being one of the cradles of civilization.
Each of the periods of Elamites, Achaemenids, Parthians, and Sassanids were creators of great architecture that over the ages has spread wide and far to other cultures being adopted. Although Iran has suffered its share of destruction, including Alexander The Great's decision to burn Persepolis, there are sufficient remains to form a picture of its classical architecture.
The Achaemenids built on a grand scale. The artists and materials they used were brought in from practically all territories of what was then the largest state in the world. Pasargadae set the standard: its city was laid out in an extensive park with bridges, gardens, colonnaded palaces and open column pavilions. Pasargadae along with Susa and Persepolis expressed the authority of The King of Kings, the staircases of the latter recording in relief sculpture the vast extent of the imperial frontier.
With the emergence of the Parthians and Sassanids there was an appearance of new forms. Parthian innovations fully flowered during the Sassanid period with massive barrel-vaulted chambers, solid masonry domes, and tall columns. This influence was to remain for years to come.
The roundness of the city of Baghdad in the Abbasid era for example, points to its Persian precedents such as Firouzabad in Fars. The two designers who were hired by al-Mansur to plan the city's design were Naubakht, a former Persian Zoroastrian who also determined that the date of the foundation of the city would be astrologically auspicious, and Mashallah ibn Athari, a former Jew from Khorasan.
The ruins of Persepolis, Ctesiphon, Jiroft, Sialk, Pasargadae, Firouzabad, and Arg-é Bam may give us merely a distant glimpse of what contribution Persians made to the art of building.
Islamic architecture of Persia
The fall of the Persian empire to invading Islamic forces led to the creation of remarkable religious buildings in Iran. Arts such as calligraphy, stucco work, mirror work, and mosaic work, became closely tied with architecture in Iran in the new era.
Archaeological excavations have provided sufficient documents in support of the impacts of Sasanian architecture on the architecture of the Islamic world.
Many experts believe the period of Persian architecture from the 15th through 17th Centuries to be the most brilliant of the post-Islamic era. Various structures such as mosques, mausoleums, bazaars, bridges, and different palaces have mainly survived from this period.
Safavid Isfahan tried to achieve grandeur in scale (Isfahan's Naghsh-i Jahan Square is the 6th largest square worldwide) knowledge about building tall buildings with vast inner spaces. However, the quality of ornaments was decreased in comparison with those of the 14th and 15th centuries.
Another aspect of this architecture was the harmony it presented and manifested with the people, their environment, and their beliefs. At the same time no strict rules were applied to govern this form of Islamic architecture.
The great mosques of Khorasan, Isfahan, and Tabriz each used local geometry, local materials, and local building methods to express in their own ways the order, harmony, and unity of Islamic architecture. And thus when the major monuments of Islamic Persian architecture are examined, they reveal complex geometrical relationships, a studied hierarchy of form and ornament, and great depths of symbolic meaning.
In the words of Arthur U. Pope, who carried out extensive studies in ancient Persian and Islamic buildings:
- "The meaningful Impact of Persian architecture is versatile. Not overwhelming but dignified, magnificent and impressive."
Persian Domes
The Sassanid Empire initiated the construction of the first large-scale domes in Persia, with such royal buildings as the Palace of Ardashir and Ghal'eh Dokhtar. With the Muslim conquest of the Sassanid Empire, the Persian architectural style became a major influence on Muslim societies, and the dome also became a feature of Muslim architecture (see gonbad).
The Il-Khanate period provided several innovations to dome-building that eventually enabled the Persians to construct much taller structures. These changes later paved the way for Safavid architecture. The pinnacle of Il-Khanate architecture was reached with the construction of the Soltaniyeh Dome (1302–1312) in Zanjan, Iran, which measures 50 m in height and 25 m in diameter, making it the 3rd largest and the tallest masonry dome ever erected. The thin, double-shelled dome was reinforced by arches between the layers.
The renaissance in Persian mosque and dome building came during the Safavid dynasty, when Shah Abbas, in 1598 initiated the reconstruction of Isfahan, with the Naqsh-e Jahan Square as the centerpiece of his new capital. Architecturally, they borrowed heavily from Il-Khanate designs, but artistically, they elevated the designs to a new level. The distinct feature of Persian domes, which separates them from those domes created in the Christian world or the Ottoman and Mughal empires, was the colorful tiles, with which they covered the exterior of their domes, as they would on the interior. These domes soon numbered dozens in Isfahan, and the distinct, blue- colored shape would dominate the skyline of the city. Reflecting the light of the sun, these domes appeared like glittering turquoise gem and could be seen from miles away by travelers following the Silk road through Persia. This very distinct style of architecture was inherited to them from the Seljuq dynasty, who for centuries had used it in their mosque building, but it was perfected during the Safavids when they invented the haft- rangi, or seven- colour style of tile burning, a process that enabled them to apply more colours to each tile, creating richer patterns, sweeter to the eye. The colours that the Persians favoured where golden, white and turquoise patterns on a dark- blue background.The extensive inscription bands of calligraphy and arabesque on most of the major buildings where carefully planned and executed by Ali Reza Abbasi, who was appointed head of the royal library and Master calligrapher at the Shah's court in 1598, while Shaykh Bahai oversaw the construction projects. Reaching 53 meters in height, the dome of Masjed-e Shah (Shah Mosque) would become the tallest in the city when it was finished in 1629. It was built as a double- shelled dome, with 14 m spanning between the two layers, and resting on an octagonal dome chamber.
