Keras monastery located near the eponymous village at an altitude of 650 meters. This monastery one of the most wonderful on Crete. It has been founded during the second Byzantine period and has murals which are dated by the 14th century.
During the Turkish ruling the Keras monastery was the rebel’s mainstay. It was the real fortress which reliably blocked the pass into the Lasithi plateau. But during the World War II, German troops established a jail on the territory of monastery.
I personally remember Keras as a picturesque place with nice views to the Crete seashore below. It’s quite and tranquil site where you can rest a little bit after hard walk on nearby mountains.
