Vlatades Monastery
Vlatades Monastery or Vlatadon Monastery (Greek: Μονή Βλατάδων) is a monastery in Ano Poli, Thessaloniki, Greece. Built in the 14th century during the late era of the Byzantine Empire, it is a UNESCO World Heritage Site along with 14 other Paleochristian and Byzantine monuments of Thessaloniki because of its Byzantine architecture and importance of Thessaloniki during early and medieval Christianity. It is believed to have been built on the former site of Jason's house. In 2005, a manuscript of Galen's Peri Alypias was discovered in the monastery's library.
