Soğanlı Valley, formerly known as Soandós is located in the Yeşilhisar district, Kayseri Province, Turkey, in the southeastern part of the region of Cappadocia.

They are responsible for around a hundred churches that have been found in the valley and connected rock-cut houses and cloisters, most of which are now buried, ruined, or used as stables.

Inside, the church has a nave with two aisles, but the frescoes have been completely destroyed.

As fertiliser they use the guano collected by the large number of dovecotes carved into the cliffs.

Since the valley is some distance from the centre of the Cappadocian region and there is no public transport link (dolmuş), it is little visited by tourists (Stand 1995).
