Anatolian Seljuk Mosque, Turkey

Seljuk architecture is the name given to architecture built during the time when the Seljuks ruled most of the Middle East and Anatolia. After the 11th century the Seljuks of Rum emerged from the Great Seljuk Empire developing their own architecture, though they were influenced and inspired by the Armenians, Byzantines and Persians. The architecture can be found in a vast area stretching from the Hindu Kush to eastern Anatolia and from Central Asia to the Persian Gulf. The homeland of the Seljuk architecture was Turkmenistan and Iran, where the first permanent Seljuk buildings were built. Unfortunately the Mongol invasions and earthquakes destroyed most of these buildings and only a few remain.  Source
