The most important church to see in the region north of Pylos is the Byzantine cathedral of Aghia Sotira (The Church of the Transfiguration). Located about 12km east of Filatra in the village of Christiani its design is said to be based on Agia Sophia in Constantinopouli. During the 11th century, the village of Christiani was the Byzantine city of Christianoupolis and the seat of the Archbishop. From the 14th century it lost its importance in the Byzantine world and in 1837 the bishopric was relocated to Kyparissia. The impressively large Byzantine church was restored after an earthquake in 1886, and is surrounded by the remains of a series of related building.
