At a distance of 3 kilometers southern to Ano Sangri, at the site of “Gyroula” are found the ruins of the sanctuary of the ancient gods Demeter and Apollo , dated in the late Geometric period, whereas the place seems to have been settled as early as in the Mycenaean times. The sanctuary was succeeded by a temple, in the 6th century b.C. The excavations of the site have brought to light numerous finds, now displayed in the small local museum on the site.

Today, we know that during the Christian era the ancient temple became a Christian basilica which was destroyed by the Saracens in the 7th century A.D. Later on, a small church dedicated to Aghios Ioannis (St. John) was constructed on the place of the sanctuary of the basilica; the small church was reconstructed in 1977, a bit southern.
