Shahrestan Bridge
The Shahrestan bridge is the oldest bridge on the Zayandeh River in Iran. The foundations date back to the Sasanian era (3rd to 7th century C.E.), but the top was renovated twice, first in the 10th century by the Buyids, then during the 11th century during the Seljuk period. Nevertheless, the architectural style is entirely Sassanian. The bridge consists of two parabolas. The vertical parabola ensures that the middle of the bridge is its highest point. The horizontal parabola produces a bend to the west, strengthening it against the flow of the river. The bridge is 107.8 metres long and an average of 5.2 metres wide. It has two tiers of pointed arches, thirteen large ones spanning the river itself, and eight smaller ones that nest between them. The purpose of the latter is to quicken the flow of water during floods, taking pressure off the structure. The Zayandeh River Zayanderud ( fa, Zāyanderud, script=Latn, from "fertile" or "life giver", and "river"), also spelled as ...

Zayanderud
Zayanderud ( fa, Zāyanderud, script=Latn, from "fertile" or "life giver", and "river"), also spelled as ''Zayandeh-Rood'' or ''Zayanderood'', is the largest river of the Iranian Plateau in central Iran. Geography The Zayandeh starts in the Zard-Kuh subrange of the Zagros Mountains in Chaharmahal and Bakhtiari Province. It flows eastward before ending in the Gavkhouni swamp, a seasonal salt lake, southeast of Isfahan (Esfahan) city. The Zayandeh used to have significant flow all year long, unlike many of Iran's rivers which are seasonal, but today runs dry due to water extraction before reaching the city of Esfahan. In the early 2010s, the lower reaches of the river dried out completely after several years of seasonal dry-outs. The Zayandeh River basin has an area of , an altitude from to , an average rain fall of and a monthly average temperature of to .

Sasanian Empire
The Sasanian () or Sassanid Empire, officially known as the Empire of Iranians (, ) and also referred to by historians as the Neo-Persian Empire, was the History of Iran, last Iranian empire before the early Muslim conquests of the 7th-8th centuries AD. Named after the Sasanian dynasty, House of Sasan, it endured for over four centuries, from 224 to 651 AD, making it the longest-lived List of monarchs of Persia, Persian imperial dynasty. The Sasanian Empire succeeded the Parthian Empire, and re-established the Persians as a major power in late antiquity alongside its neighbouring arch-rival, the Roman Empire (after 395 the Byzantine Empire).Norman A.

Buyids
The Buyid dynasty ( fa, آل بویه, Āl-e Būya), also spelled Buwayhid ( ar, البويهية, Al-Buwayhiyyah), was a Shia Iranian dynasty of Daylamite origin, which mainly ruled over Iraq and central and southern Iran from 934 to 1062. Coupled with the rise of other Iranian dynasties in the region, the approximate century of Buyid rule represents the period in Iranian history sometimes called the 'Iranian Intermezzo' since, after the Muslim conquest of Persia, it was an interlude between the rule of the Abbasid Caliphate and the Seljuk Empire. The Buyid dynasty was founded by 'Ali ibn Buya, who in 934 conquered Fars and made Shiraz his capital. His younger brother Hasan ibn Buya conquered parts of Jibal in the late 930s, and by 943 managed to capture Ray, which he made his capital. In 945, the youngest brother, Ahmad ibn Buya, conquered Iraq and made Baghdad his capital. He received the ''laqab'' or honorific title of ''Mu'izz al-Dawla'' ("Fortifier of the State"). The e ...

Seljuq Empire
The Great Seljuk Empire, or the Seljuk Empire was a high medieval, culturally Turko-Persian, Sunni Muslim empire, founded and ruled by the Qïnïq branch of Oghuz Turks. It spanned a total area of from Anatolia and the Levant in the west to the Hindu Kush in the east, and from Central Asia in the north to the Persian Gulf in the south. The Seljuk Empire was founded in 1037 by Tughril (990–1063) and his brother Chaghri (989–1060), both of whom co-ruled over its territories; there are indications that the Seljuk leadership otherwise functioned as a triumvirate and thus included Musa Yabghu, the uncle of the aforementioned two. From their homelands near the Aral Sea, the Seljuks advanced first into Khorasan and into the Iranian mainland, where they would become largely based as a Persianate society. They then moved west to conquer Baghdad, filling up the power vacuum that had been caused by struggles between the Arab Abbasid Caliphate and the Iranian Buyid Empire. The subs ...

Bridges In Iran
A bridge is a structure built to Span (engineering), span a physical obstacle (such as a body of water, valley, road, or rail) without blocking the way underneath. It is constructed for the purpose of providing passage over the obstacle, which is usually something that is otherwise difficult or impossible to cross. There are many different designs of bridges, each serving a particular purpose and applicable to different situations. Designs of bridges vary depending on factors such as the function of the bridge, the nature of the terrain where the bridge is constructed and anchored, and the material used to make it, and the funds available to build it. The earliest bridges were likely made with fallen trees and stepping stones. The Neolithic people built boardwalk bridges across marshland. The Arkadiko Bridge (dating from the 13th century BC, in the Peloponnese) is one of the oldest arch bridges still in existence and use. Etymology The ''Oxford English Dictionary'' traces ...

Architecture In Iran
Iranian architecture or Persian architecture (Persian: معمارى ایرانی, ''Memāri e Irāni'') is the architecture of Iran and parts of the rest of West Asia, the Caucasus and Central Asia. Its history dates back to at least 5,000 BC with characteristic examples distributed over a vast area from Turkey and Iraq to Uzbekistan and Tajikistan, and 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". In addition to historic gates, palaces, and mosques, the rapid growth of cities such as the capital Tehran has brought about a wave of demolition and new construction. Iranian architecture displays great variety, both structural and aesthetic, from a variety of 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" ...

Buildings And Structures In Isfahan Province
A building, or edifice, is an enclosed structure with a roof and walls standing more or less permanently in one place, such as a house or factory (although there's also portable buildings). Buildings come in a variety of sizes, shapes, and functions, and have been adapted throughout history for a wide number of factors, from building materials available, to weather conditions, land prices, ground conditions, specific uses, monument, prestige, and aesthetic reasons. To better understand the term ''building'' compare the list of nonbuilding structures. Buildings serve several societal needs – primarily as shelter from weather, security, living space, privacy, to store belongings, and to comfortably live and work. A building as a shelter represents a physical division of the :Human habitats, human habitat (a place of comfort and safety) and the ''outside'' (a place that at times may be harsh and harmful).

Sasanian Architecture
Sasanian architecture refers to the Persian architectural style that reached a peak in its development during the Sasanian era. In many ways the Sasanian Empire period (224–651 CE) witnessed the highest achievement of Iranian civilization, and constituted the last great pre-Islamic Persian Empire before the Muslim conquest. Much of Sasanian architecture was adopted by Muslims and became part of Islamic architecture. The Sasanian dynasty, like the Achaemenid Empire, originated in the province of Persis ( Fars). They saw themselves as successors to the Achaemenians, after the Hellenistic and Parthian dynasty interlude, and perceived it as their role to restore the greatness of Persia. Origins In reviving the glories of the Achaemenian past, the Sasanians were no mere imitators. The art of this period reveals an astonishing virility. In certain respects it anticipates features later developed during the Islamic period. The conquest of Persia by Alexander the Great had inaugura ...
