During the Byzantine period, many Christian churches were founded in Leros. Of unique interest is the church of Agia Paraskevi which was the old Metropolis of the island. It is found on the edge of the settlement, close to a path that leads on top of the castle.
Around the capital of Leros, in Partheni quarter lies the early Christian vaulted church of Agios Georgios. Within the walls of the medieval castle in Chora, stands the church of Our Lady of the Castle famous for the miraculous icon. It was built in the 10th century and hosts an ecclesiastical museum with valuable icons and frescoes.
In the village of Lakki, in the middle of a pine tree forest lies the Monastery of Agios Ioannis which holds significant historical interest. Other churches in Leros are those of Agia Marina, Agios Isidoros and the church of Panagia Kavouradena.
Church of Agios Isidoros
The lovely church of Agios Isidoros stands on the islet of Alinda that is connected to the land by a narrow passage. The little chapel is built on the site of an ancient temple, the ruins of which can still be seen behind the altar. The view from the church is very beautiful, especially in the sunset.
Church of Prophet Elias
This is a nice small chapel beneath the Castle of Pandeli. It is constructed by the sea and gives an amazing view of the sunset.
