The church was renovated in 1898, with new domes being added. Exarch Joseph I of Bulgaria was buried immediately outside the walls of St Nedelya in 1915. The church was razed in the assault in 1925 that claimed over 150 victims. After the assault, the church was restored to its modern appearance between the summer of 1927 and the spring of 1933 (once again inaugurated on 7 April 1933). It was almost erected anew as a temple 30 m in length and 15.50 m in width and featuring a central dome that made it 31 m high. The gilt iconostasis that survived the bomb attack was returned to the church.
