There is a region marked on several maps as "Area A". In at least one text it is indicated there was a church here, my guess is this is it. There was a structure covering some fresh digs, I had the impression this was an atrium, it might well have been some other structure like an altar.

You can find the area on some pictures using View Map.

A helpful source was On the Lycian Way, a book sold at museums in the area.
