Batheos Rhyakos Monastery was a Byzantine-era monastery near medieval Trigleia in Bithynia (modern Tirilye in Turkey). It is known locally as Aya Sotiri.[1]
The church of the monastery had an east-west oriented rectangular naos, with a rounded apse in the north part of the east end and a narthex at the west end.[2] The building’s exterior dimensions measured 16 by 9 meters.[3]
In the 1880s, the monastery was described as “neglected,” with only the four walls of the church and some scattered columns remaining.[4] However, In 1910, it seems to have been described as “recently restored.”[5]
When the area was cleared of brush and mapped in 1987, the monastery was in ruins and mostly rubble; then, in 1988, the landowner cleared the area with heavy machinery and built a shed.[6] In 2017, piles of stones from the walls remained.[7]
The monastery is also known as the Monastery of the Transfiguration of Christ the Savior (Greek: Μονή Μεταμορφόσεως Σωτήρος Χριστού), the Soteros or Savior Monastery (Μονή Σωτήρος).
