Built right into the cliff beneath the Venetian fortress, tiny Agios Spyridon has enough atmosphere to fill a cathedral. This Byzantine chapel is filled with richly painted icons, swinging bird candleholders and the sound of the nearby pounding surf. You’ll see pairs of slippers, baby shoes and sandals in crevices in the rock wall, left as prayer offerings for the sick. Find the chapel at the top of a staircase on the western side of the fortress. Opening hours are erratic.
