Ortaköy - Virgin Mary Church

The Ortaköy Virgin Mary Armenian Church (also known as the "Dolmabahçe Armenian Church") is an Armenian Apostolic church located in the Ortaköy neighborhood of Istanbul, Turkey. It was constructed in 1836 on the orders of Armenian Patriarch of Constantinople, Hovhannes VII. The church was designed by the architect Garabet Amira Balyan, who was also responsible for designing many other notable buildings in Istanbul.

The church is located on the European side of Istanbul, on the banks of the Bosphorus Strait, and is considered one of the city's most iconic landmarks due to its picturesque location and distinctive architecture. The church's design is a combination of traditional Armenian and Ottoman architectural styles, and its main feature is its distinctive hexagonal tower, which is topped with a dome and four smaller domes.

The church underwent a major restoration in 1960, during which many of its original features were restored or reconstructed. Today, it is a popular tourist destination and a site of pilgrimage for the city's Armenian community.
