Protestant church of Saints Peter and Paul in Karlovy Vary, Protestant church in Karlovy Vary, Czech Republic

The Protestant church of Saints Peter and Paul is a single-nave church on the right bank of the Teplá, about 100 metres east of the Imperial Baths. Its present form dates from 1893–1894, when Leipzig architect Julius Zeissig gave it a neo-Romanesque face: a square tower with an octagonal upper storey, clock and bells, a polygonal apse, and a wooden coffered ceiling inside.

The church was built in 1854–1856 in Neoclassical style under architect Gustav Hein, on land donated by Countess Hermine von Schaumburg-Lippe for non-Catholic spa guests; it was consecrated on 1 July 1856 and dedicated to Saint Peter alone. After the Austrian Protestant Patent of 1861, a tower and choir were added in 1864–1866, and in 1893–1894 Leipzig architect Julius Zeissig gave it its Neo-Romanesque form. Since 1952 it has been used by the Czechoslovak Hussite Church.

The church was built for non-Catholic spa guests: the land came from Countess Hermine von Schaumburg-Lippe, and Hanover's King George V took on its patronage. Since 1952 it has belonged to the Czechoslovak Hussite Church, which still holds Sunday services and organ concerts here. In the entrance hall hang a plaque with a kneeling Petr Chelčický by František Bílek and a bronze bust of Karel Farský.

The church stands on the right bank of the Teplá river, about 100 metres east of the Imperial Baths (Císařské lázně) on Mariánskolázeňská street. The former parish house, about 30 metres east, now operates as Villa Basileia guesthouse. Organ concerts are held here alongside Sunday services.

The church keeps its nickname "evangelical" from its Lutheran origins. In the entrance hall hangs a bronze bust of Karel Farský, founder and first patriarch of the Czechoslovak Hussite Church, which has used the building since 1952. A plaque shows Peter Chelčický kneeling, carved by František Bílek.
