This unusual gem belonging to the Saronic islands is located to the east of the Peloponnese. There are no cars here. Named after the island, the harbour town is layered up the slopes of a mountainous bay. You may be surprised to see beautiful stone mansions. These are traditional here, as are the multi-coloured caïques along the quays. Further along the shore, you will discover the Historical Archives Museum. Collections from Athens National History Museum are exhibited in the elegant villa Koundouriotis.
