The cave church is very similar to the ones in Cappadocia, where most of the frescoes can be dated to the 13th century. Sille is a small village close to Konya in central Anatolia. The oldest evidence of a settlement dates back to the Phrygians in the 8th century BC. Then the Romans came and even apostle Paulus was here. Helena, the mother of emperor Konstantin, visited Sille on her pilgrimage to Jerusalem in 327 and founded the church Agia Eleni. Until the peoples exchange between Greece and Turkey in 1923 Sille had an eminent Greek orthodox and Armenian population. Reportedly there were about 60 churches, partly private. Today there are still existing the Agia Eleni, the Süt Kilisesi (milk church) and several cave churches. But there are also old mosques, Ottoman houses, hamams and an aqueduct from the 19th century. Today there are lots of restauration works to attract tourist.
