Trinitatis Church, Gothic Revival church in Charlottenburg, Germany.

Trinitatis Church is an evangelical church on Karl-August-Platz in Charlottenburg, built in red brick in Gothic Revival style on a Greek-cross plan. Its west facade is dominated by a 70-metre tower with a clock face and a steep pointed spire. Inside, a 15-metre-wide cross vault spans the nave, and a 5.40-metre wooden crucifix by Otto Flath stands in the chancel.

The Luisenkirche parish planned a second church for Charlottenburg's southern district; the foundation stone was laid on 18 October 1896 under the patronage of Empress Auguste Viktoria. Architects Johannes Vollmer and Heinrich Jassoy designed the red-brick Gothic Revival building on a Greek-cross plan. It was consecrated on 11 December 1898 in the presence of Kaiser Wilhelm II and Auguste Viktoria, and became an independent parish in 1899.

The name refers to the Trinity, and the church was consecrated in 1898 as a daughter of the Luisenkirche parish. The interior holds a 5.40-metre wooden crucifix carved by Otto Flath, given to the congregation after 1962, along with his mourning war memorial and baptismal font. Stained-glass windows by Berlin artists Kirchberger, Bader, Berndt and Ebeling date from the 1960s redesign.

The church stands centrally on Karl August Square and is easily visible from the street. It is good to check ahead for visiting hours and current events before arriving.

The tower survived World War II largely intact while the rest of the church was heavily damaged, so it was secured first after the war. Inside, a 5.40-metre wooden crucifix by Otto Flath dominates the chancel; the sculptor also made the congregation's war memorial and baptismal font.
