What to See in Leros
One of the most striking features of Leros is the Kastro of the Virgin Mary (Panagia Kastrou) that towers above the island's capital Platanos. It dates back to the 11th century, and was a stronghold for the Knights of St. John.
Here, there is also a museum with findings from various time periods, as well as an old church.
In Platanos stands the old cathedral Agia Paraskevi. The town itself is nice for strolling around in, and most of the houses were built in the 1800's.
In Alinda you can visit the church of Agios Isidoros that was built on top of an ancient temple. There is also a castle here the Belenis tower which is open to the public, and holds some interesting finds from the island, including parts of the warship Queen Olga that was sunk here by the Germans in 1943. The island's first printer can also be seen here.
Just outside Partheni before the airport of Leros there are the remains of a temple of Artemis.
In Xerokambos you can visit the church of Panagia Kavouradina ("The Virgin Mary of Crabs"). Legend has it that a fisher man found it here, and was immediately cured from a crab bite on his hand. In a dream he was told by a woman dressed in black to return the icon to where it was found, and so the church was built. Near Xirokampos are the ruins of a Prehistoric citadel at Paleokastro. Don't miss a visit to the war museum of Leros build in a war tunnel at the area of Merkia a few hundred meters west of the port of Lakki. In the museum there are weapons, uniforms and other items from the second world war.
