Church of Saint John the Baptist, Gothic church in Kolín IV, Czech Republic.

The Church of Saint John the Baptist is a single-nave, oriented stone building with plastered walls, now without a tower, standing partly below ground level near the Masaryk Bridge over the Labe. Its rectangular presbytery measures 5.42 by 4.3 metres and has a cross-vaulted ceiling; a Gothic window is walled up in the south wall, the original Gothic window remains on the east side, and the triumphal arch is pointed. The interior is Baroque in style, now with Orthodox icons and an iconostasis separating the presbytery.

The church was built at the turn of the 13th and 14th centuries on the road from Kolín to Kutná Hora; the first written mention dates from 1359. It was rebuilt in late Gothic style in 1589, damaged during the Thirty Years' War and repaired in 1652 and 1665. In 1747 it received late Baroque features, and in 1952 it was taken over by the Orthodox Church.

The church is named after Saint John the Baptist, whose life is depicted in ceiling frescoes and whose damaged statue stands on the facade. Since 1952 the Orthodox Church has rented it, and an iconostasis installed that year now hides the 1747 main altar. Services grew with the arrival of Russian residents in Kolín in the early 21st century.

The church stands near the Masaryk Bridge over the Labe, partly below the level of the surrounding terrain after earlier construction work. It has no tower, and the statue of Saint John the Baptist on the facade is badly damaged. The Orthodox congregation has rented it from the Catholic Church since the 1950s.

The church stands on a former cemetery abolished in 1882; an obelisk there marks a mass grave of Prussian soldiers from the Austro-Prussian War of 1866. Building work also left the church partly below the surrounding ground level.
