The 15th-century fortified monastery of Moni Vronta is on a mountain overlooking the sea and the hilltop village of Vourliotes. Few if any monks live there these days, but a caretaker is usually about; if the gate is locked, try knocking -- one of the soldiers from a nearby post may be around to let you in. Ask to see the spileo (cave), an old chapel, built into the thickness of the outer wall that holds a collection of ancient objects, some from the time of the monastery's founding.
