[1] According to tradition it was founded in the time of Justinian I (r. 527–565), but was rebuilt in its present form by Byzantine emperor Alexios I Komnenos (r. 1081–1118).
The modern main church (katholikon) dates largely to the 16th century, with some parts from a 14th-century structure.
The outer walls are decorated with large numbers of ancient and Byzantine spolia, but the surviving interior frescoes date to 1758.
[1] Modern archaeological excavations have discovered traces of the Komnenian-era katholikon underneath.
[1] The monastery was destroyed by fire in 1868 and the katholikon was left ruined for over a century after; it was restored in the early 2000s by the 7th Ephorate of Byzantine Antiquities with European Union funds.
