Until 1870, in place of the church Holy Trinity there was a small old church and a school. The desire of the entire society in the city was to have a new place of worship, so between 1893-1898, the architect Vyachelslav Gavarda made a new project, and the construction was done by the entrepreneur Ivan Okoliyski of Tryavna, under the patronage of the town hall. The construction was completed in 1912, resulting in a tall, massive church made of stone and brick, in the form of a majestic basilica with three naves, an apse and pronaos, and three domes. The columns in the nave are of Roman origin. The iconostasis is high, and the icons come from Galicnik (Macedonia) school masters Danail Nestorov, his cousin Oventiy Isachev, Aleks Vassilev and Adolf Sedov. The interior was painted by prof. Iliya Pefev, also descendant of the masters of the Debar School, between the years1940-1946.
