Agia Marina, the capital of the island, is divided into three residential areas: to the North is the village of Agia Marina, tucked between the Castle and Merovigli hill is Platanos and near the coast, Panteli extends east towards the bay.
In Platanos the beautiful two-storey mansions still stand, scattered in picturesque alleys. Walking around the village - ideally in the afternoon – stop by Avlaki, a district full of fountains gushing cool water from the spring of Paliaskloupi.
Walking down to the port of Agia, the roman fortress Brouzi (or Bourtzi) appears before you. On the way to Alinda, you will find the famous Watermill of Agia Marina, one of the most photographed sights of the island.
The Folklore Museum in Alinda is housed in the Bellenis Tower (1925), a sample of Italian eclecticism with Romanesque and neo-Gothic elements. It was the country house of the Egyptian benefactor Parisi Belleni, and turned into a German hospital later on.
While in Agia Marina, it is also worth visiting the Archaeological Museum of the island with findings and objects (vases, mosaics, tombstones) from the classical to the early Christian era.
Above Agia Marina, at the top of hill Apityki, stands the Castle of Panagia, with panoramic views of the Aegean Sea. This is a byzantine castle, built in the 10th - 11th century, on the west side of which is the church of Panagia with the wood-carved iconostasis of the 18th century. Going up to the castle you will find the picturesque neighbourhood with the six windmills, the oldest of which dates back to the 17th century.
Another attraction on the island is Lakki, a living island museum, a wonderful example of the Italian Rationalist Architecture of the Dodecanese. There are several, significant buildings in the area: from the Primary School (1936) to the waterfront, the cinema and the hotel "Leros", the outdoor market (1934), the Clock Tower, the palacinos of the Italian navy officers, the Hotel of Rome, etc. Lakki is the largest natural port in the Mediterranean, which is why it was used as a base of the Royal Italian Navy. The Italians remained on the island for 31 years, with Mussolini considering Leros as one of the most strategic points of Italian sovereignty in the Mediterranean.
In the list of museums, you should definitely add the War Museum of Leros. It is housed in the restored military tunnel of Merikia, an underground tunnel built by the Italians for their supply during the Second World War. The surrounding area hosts military cars, trucks, and planes.
Just 2 km from Lakki, there is a small, picturesque fishing village, Xirokampos. At its top stands the imposing Castle of Lepides or Palaiokastro, the oldest one surviving on the island.
Among the most picturesque sites on Leros are three churches: The small chapel of Agios Isidoros in the bay of Gourna, built on a rock that is connected to the mainland with a small jetty, an ideal spot to marvel at the sunset. Panagia Kavouradena, a chapel carved in a rock, where it is said that the icon of the Virgin Mary was found, and Saint Matrona-Kioura, in the bay of Partheni, exiles during the Dictatorship.
When visiting Partheni don’t forget to stop at the remains of the ancient temple of the goddess Artemis dating back to the 7th century BC.
