The Center of Mosque Studies - Completed in 1220, the Alaeddin Camii is the oldest known Seljuk mosque in Turkey. It is built into the hill that forms the citadel of Konya; its pointed arch and round domes atop two tombs are prominent features in Konya's cityscape. With the exception of Izzeddin Keykavus, all of the Seljuk sultans after 1156 are interred in the complex.
Its oblong, hypostyle plan is influenced by Arabic classical architecture, but it is very much a Seljuk building. In fact, it is an agglomeration of two major rebuilding campaigns undertaken by both Sultan Izzeddin Keykavus and Sultan Alaeddin Keykavus.;
