The first buildings (1088-1093) were the Katholikon, the cistern (tank), some cells and a large part of the walls. In the 12th century the chapels of Our Lady and Saint Christodoulos were built. In the 16th century new and important buildings were constructed: the Chapel of the Holy Cross, the Chapel of the Apostles, the Chapel of St. Basil and the sacristy next to the church. In the last decade of the 17th century a large building project (named after the Metropolitan of Karpathos, Grimanis Neophytos) took place and the monastery acquired the appearance it has nowadays.
