Seljuk-era mosques were built during the Seljuk Empire, which flourished from the 11th to the 14th centuries. These mosques are known for their grand architectural features, including large domes, intricate tile work, and expansive courtyards. They often served as centers for community gatherings and religious activities. The design of Seljuk mosques typically includes a large prayer hall, a minaret for the call to prayer, and decorative elements like arabesques and calligraphy. Notable examples include the Great Mosque of Isfahan and the Sultan Han Mosque, which showcase the artistic and cultural achievements of the Seljuk period.
