Among the villages Chalki and Moni is one of the most important Christian monuments on the island. One of the oldest and most beautiful churches of Naxos, Panagia Drosiani attracts the eye of its visitors with its rare architecture.
It is a three-winged Byzantine church with a dome, built with rough stones and slabs on its roof. On its north side are three one-room chapels with domes. It dates back to the 6th century and was a Catholic monastery.
In its interior were three layers of frescoes of unique value, of which the first two were removed and transferred to museums. These that we see today are the oldest and date back to the 6th century and the first half of the 7th century. A particularly interesting sight is the dual representation of Christ in the dome, who is represented as a young man with little facial hair and a mature man with a beard.
