Friedenskirche Frankfurt, Gothic church in Frankfurt (Oder), Germany

The Friedenskirche is the oldest stone building in Frankfurt (Oder), begun around 1226 as the Nicolaikirche. Its four-bay nave walls from around 1300 survive, and the two-tower neo-Gothic west facade, 55 metres high, was added in 1890–1894 to designs by Friedrich Adler.

The Nicolaikirche was built around 1226 for merchants at a narrow Oder crossing; its four-bay nave followed around 1300. Secularised in November 1539, it became a grain store in 1557 and housed prisoners and the sick from 1600 to 1650. In 1657 the Great Elector gave it to the Reformed congregation, which held its first French service in 1686. It was renamed Friedenskirche in 1929.

The name Friedenskirche (Peace Church) dates from 1929, when the former Reformed church was renamed. French Huguenots who settled in Frankfurt (Oder) held their first French-language service here in 1686, and the building later served as a burial place for officials and army officers. Since 1994 the Förderkreis Oekumenisches Europa-Centrum has worked to turn it into an interdenominational meeting place.

The building is accessible to visitors and hosts regular gatherings and cultural events managed by the Oecumenisches Europa-Centrum organization. Check ahead for current opening hours, as these may vary depending on events and the season.

The north tower holds three bronze bells cast in 1618, 1673 and 1674; the two oldest by Franz Sebastian Voillard are the oldest working bells in Frankfurt (Oder). The 1618 bell was recast in 1747 after cracking, and a 1931 replacement stands in for the original melted down in World War I.
