Near Ano Poli’s Byzantine Walls, the salmon-coloured arches of this secluded monastery are a relaxing place for a stroll. Thought to have been founded around 1351 by the pious brothers Vlatades, this monastery was significant for Hesychasm, a controversial movement based around solitary spiritual reflection. Its foremost 14th-century proponent, St Gregory Palamas, is depicted in a fresco here.
A now-lost imperial chrysobull (gold-sealed decree) of the Byzantine Empress indicates Anna Paleologina endowed Vlatadon, which still preserves a rich archive of documents dating to the 15th century.
