It was constructed during the 19th century following a Bulgarian nationalist movement. It was closed in 2011 and reopened to the public in 2018 after a large-scale renovation. Showcasing both neo-Byzantine and neo-Baroque architectural influences, the building is made up of cast iron.

St.George's Cathedral is an Eastern Orthodox church situated in Fener in the Fatih district of Istanbul.

The interior of the church house a fragment of the Pillar of the Flagellation. The church has been damaged several times while also enduring a terrorist attack in 1997. Hardly any parts of the original structure remain due to the multiple renovations over the years but that has not deterred the exemplary magnificence of the structure which is still a common place of pilgrimage for many.
