Trinitatiskirche, Gothic Revival church in Johannstadt, Dresden, Germany

Trinitatiskirche is a roofless red-brick ruin with reddish-brown stone trim in Johannstadt. Its full-height side walls frame an open nave; the far wall has a large stone arch band above three tall arched windows, the outer two blind and the centre open. Two dark domed towers with green finials rise at either side, and a dark rectangular canopy runs along the lower right wall.

The parish commissioned architect Karl Barth, and construction ran from September 1891 to October 1894, with consecration on 17 October 1894. The air raids of 13/14 February 1945 burned out the nave and destroyed the roof and interior; the tower escaped with little damage. In the late 1960s the parish blocked demolition by planning a worship room and conference centre, and from 2020 to 2022 the ruin was converted into a youth church.

The name comes from the Trinitatisfriedhof beside the plot, which the city gave the parish for the church. Since 25 March 2022 the ruin has been Dresden's Jugendkirche, run by the Protestant youth of Dresden under the motto "Raum für Zeit für Dich". A 9 by 9 metre glass cube now stands in the roofless nave, letting events go ahead whatever the weather.

The roofless nave is open to the elements, so visits depend on the weather; the glazed 9-by-9-metre cube inside allows events in any conditions. The site is at Trinitatisplatz in Johannstadt, and the tower holds a new spiral staircase and rooms for youth work. The building has been run since 2022 by the Evangelische Jugend Dresden as the Jugendkirche.

The tower clock and bells survived the 13/14 February 1945 bombing and were kept working; the four original bells from C. Albert Bierling were melted down as a metal donation in World War I, and three cast-iron bells from Schilling & Lattermann followed in 1920. Since 25 March 2022 the ruin has been the Jugendkirche Dresden, with a 9-by-9-metre glass cube standing inside the roofless nave.
