The holy monastery of Agh. Triada is archaeologically interesting and is magically situated high above the village of Trapeza near the town of Diacopto.
It is built on the ruins of an ancient temple dedicated to the Earth Goddess. A dome survives which is a conical structure much like a Mycenean tomb. It dates from the late period and is 6.2 meters high. There is also another more recently constructed dome.
The ancient dome has been transformed into a church and has wall paintings dating from 1757. According to Koryllon the monastry was founded in 1936 AD.
Today one can visit the monastry and enjoy the hospitality offered by the single monk who resides there.
