A unique, tiny chapel dedicated to the Virgin Mary, was built inside a large cave northwest of Pythagoreio. In the church there is a marble icon of the Virgin, whose appearance on it is unclear. Next to the chapel is a small pool of what is said to be holy water. Spiliani (or Virgin of the Grotto) is also known by locals as ‘Kaliarmenissa’ and is considered to bring good luck to travellers.
