Agia Pakou Church of Syros
In Galissas, over the homonym beach, stands alone the Catholic chapel of Agia Pakou. Located on the highest spot of the area, it is white with blue details. The route to the church is difficult, with many stairs and a gnarled path, though the view from above will definitely reward you. Gaze at the sunset and make sure to visit it again on its feast day and join the festival.
