The Church of the Virgin Mary is the only church open for worship in Bozcaada, which is located in the center of the Greek Quarter, and was built in 1869. The churchyards also include a four-storey bell tower, built in 1895, 23.8 meters tall and restored several times, because it was damaged and eroded With the passage of time, the last of these restorations was in 2006. Your only chance to see the church from the inside is to visit at the time of the prayer rites that are held every Sunday, at eight in the morning, because the church does not open its doors to visitors at any other time.
