The Varlaam Monastery, dedicated to All Saints, is located in Thessaly, north of Trikala. It is the second largest of the Meteora monasteries, perched atop a 373 m high rock, and it is truly a sight to see. It was built in 1350 by a monk, Varlaam, and embellished in 1518 by Theophanis and Nektarios Apsaras, brothers from Ioannina. It took the men 22 years to gather the materials needed to build the monastery. It was then completed in 20 days. The 16th century frescoes in the monastery are the main attraction. They cover walls, beams and pillars. You can reach the monastery by climbing 195 stairs.
