Ypsilotera Monastery, Former Orthodox monastery in Meteora, Greece.

Ypsilotera Monastery is a ruined former Greek Orthodox monastery on Ypsilotera Rock in the Meteora complex near Kalabaka. The rock stands 585.7 metres above sea level, beside the geological formation called the Devil's Tower, between the monasteries of St. Nicholas Anapausas and Varlaam. A lower adjacent rock also holds monastery buildings.

The monastery was founded in 1347 by Paschalis of Kalambaka and grew into an important center for copying religious manuscripts. It remained active during the medieval period before eventually being abandoned in later centuries.

The monks here were renowned for their meticulous manuscript work, dedicating themselves to copying and preserving religious texts by hand. Their scholarly work made this monastery a center of learning that drew attention from pilgrims and visitors across the region.

The best way to view this monastery is from the viewing points at Great Meteoron or Varlaam monasteries, which sit on higher rocks nearby. From these vantage points, the abandoned structure becomes clearly visible for observation and photography.

The monastery's other name, Kalligrafon ("of the calligraphers"), comes from the manuscript copying that made it known. Its rock, Ypsilotera, rises 585.7 m above sea level and stands beside the "Devil's Tower," a rock formation between the monasteries of St. Nicholas Anapausas and Varlaam. A lower rock adjoins Ypsilotera Rock.
