Northwest of Pythagoreio, in a near distance, in a large cave a small chapel is located which is dedicated to the Virgin Mary. In the chapel there is a marbel icon of the Virgin Mary, which is so old that it is difficult to make out the figure.
Next to the church you will find Holly Water. Outside the cave there is a church dedicated to Saint George and a few chambers. The church of Siliani belongs to the Monastery of Hazoviotissa of Amorgo.
Spiliani is also known as Kaliarmenissa to the locals. Access to the Monastery is very easy with a private or rental vehicle from Pythagoreio, even by taxi.
