Metropolitan Church of Saint Nicholas

The impressive Metropolitan Church of St. Nicholas, the patron saint of Alexandroupolis, is located in the centre of the city, on its unique hill. Built to replace a wooden chapel that had existed on the site since 1860, it was founded in 1892 by architects and craftsmen who had been invited from Constantinople, while the cost was covered by fundraisers that had raised large sums for the time. It was inaugurated in 1901 and lived, together with the city's inhabitants, through all the historical events that followed, playing an important intellectual role. In 1920, the protocol of the city's union with Greece was signed inside the church. Dedeagats was named after the Macedonian King Alexander and renamed Alexandroupolis.

The church serves as a place of worship and prayer, but at the same time it is an important architectural monument. Its style is basilica cruciform with a dome, it is built with stone and its two bell towers date back to 1908. The iconostasis is the same as that of the Holy Trinity of Constantinople and was made in the 1930s. Within the church are kept important icons of the Virgin Mary, the 13th century wood-carved Virgin Mary Trifotissa, the Virgin Mary Maurofourousa brought to the country by refugees from Eastern Thrace and the Virgin Mary the Liberator, as well as a fragment of the relic of St. Nicholas and relics of Neomartyrs and Saints.
