Develi, formerly known as Averak or Everek, is a municipality and district of Kayseri Province, Turkey.

[1] The historical name of the town is Everek and it is called Averak (ruin) in Armenian.

A historian and geographer who lived in the fourteenth century, gives the name of the butcher Mustavfi as Davalu.

According to historical sources, cultural traces of civilizations that lived in Develi between 2500-2000 BC have been found.

This discovery led to an ongoing divergence of opinions between the national authority for foundations, responsible for maintenance of mosques in Turkey, which is in favor of covering the cross and Virgin Mary figures again, and Kayseri Governorship's cultural protection unit which advocates a restoration to their state of origin, a move that would put an end to the edifice's use as a mosque, this use currently being restrained to a part of the building until an official decision is made.
