Spend the afternoon exploring the charming village of Ano Mera (reached by bus from the Old Port). It is quieter and more peaceful than Chora, and has a few historic sites worth visiting, such as the ruins of Gyzi Castle, built under Venetian rule, and the intact Paleokastro Monastery, both of which offer fabulous views from their higher vantage points. One of the most impressive, however, is the Panagia Tourliani Monastery, built in 1542, and covered inside with brightly painted icons, an altar screen painted by Florentine artists, and dragon-shaped incense holders.
After the heat of the day has died down, take a trip to Delos. You’ll find a range of tours departing from the Old Port at different times, and you’ll have a couple of hours to explore this 5,000 year old archaeological, and mythological, site. Believed to be the birthplace of twin gods Apollo and Artemis, it was inhabited as far back as 3000BC, and you can see the remains of amphitheatres, temples, public squares, marketplaces and several sculptures. One such sculpture is half a phallus, all that’s left of the symbol of wine god Dionysus, while a series of lions line a terrace which once led to Apollo’s shrine.
