Bolnisi Kirche – A Lutheran Church (presently Bolnisi Sports and Fitness Complex) is situated at the intersection of Giorgi Saakadze and Merab Kostava streets.
 In 1854 the church was built in Gothic style and it stood on the main square of the city. Unlike an Orthodox church, its altar is directed southwards. The longitudinal walls are consolidated by five pairs of two-stepped buttresses. Between them are five tall right-angled windows bound by a pediment and an arched hood. There is a pentagon apse on the south, whose four facets featured tall windows ending with helmet-like arches (nowadays the windows are built up, while a door is arranged in the central facet). On the north the church had a three-story bell-tower and a porch was arranged on its ground floor.
 In the 1970s the bell-tower was pulled down and the porch vanished in the two-storey spaces annexed to the north and east of the church. Due to this and some other alterations, the Lutheran church lost its basic features. The interior, which has now been converted to a sports hall, once was a space covered with a wooden vault which had an altar open with an arch. Two pairs of wooden columns divided the hall into three naves and an open gallery supported by the same columns ran around the sides of the hall.
 The former Lutheran church was granted the status of an immovable monument of cultural heritage.
