Church of the Saviour, Thessaloniki

The Church of the Transfiguration of the Saviour (Ναός Μεταμορφώσεως του Σωτήρος, Naós Metamorphóseos tou Sotíros) is a 14th-century Byzantine chapel in Thessaloniki, Greece. It is a UNESCO World Heritage Site as one of the Paleochristian and Byzantine monuments of Thessaloniki.

History
The church has been dated to about 1350, based on a coin found within its dome during archaeological investigations and restoration work following the 1978 Thessaloniki earthquake.

Construction and furnishings
The lower part of the chapel is made of unhewn stone, the upper part of brickwork. It consists of a central room in the form of a tetraconchos, inscribed in a square and vaulted by a dome on a comparatively high tambour structured by archivolts and half-columns.
