Friedenskirche Grünau, Church building in Grünau, Germany.

Friedenskirche Grünau is a north-south oriented church clad in Nesselberg sandstone and red brick, built in a Märkisch style recalling late Romanesque models. A 35-metre square tower rises at the southwest corner, its stone base topped by red brick with louvered openings, a clock face and a steep pyramidal roof. The south side has a polygonal entrance block with the main portal and organ gallery, and two transverse saddle roofs with blind gables on the west side.

Built 1904–1906 to plans by Ludwig von Tiedemann and Wilhelm Walther, the church arose under the Church Building Association and the patronage of Empress Auguste Viktoria. On 23 April 1945 Soviet troops entering Grünau looted and destroyed much of the interior. After provisional roof and window repairs, services resumed on Bußtag 1948; a 2006 restoration uncovered F. W. Mayer's interior painting.

The forecourt was renamed Don-Ugoletti-Platz in 2008 after Don Ugoletti, a priest from Albinea, Treptow-Köpenick's partner town in Italy, who recorded the Villa Rossi events in his diary and ensured five executed Wehrmacht soldiers, among them Hans Schmidt of Johannistal, received a Christian burial. The baptismal font of Wealden sandstone bears the inscription "Gestiftet von Ihrer Majestät der Kaiserin Auguste Victoria".

The church stands at the end of Eibseestraße on Don-Ugoletti-Platz, in the Grünau district of Treptow-Köpenick. The square was named after Don Ugoletti in 2008. The 35 m tower marks the southwest corner, with the entrance porch and its three-sided polygon on the south side.

The tower clock was faithfully restored in 1999 for Grünau's 250th anniversary. The baptismal font of Wealden sandstone bears the inscription "Gestiftet von Ihrer Majestät der Kaiserin Auguste Victoria". Since 2008, seven-armed candlesticks by Achim Kühn, rebuilt from old photographs, stand beside the altar.
