Trinitatiskirche, Protestant church in Langholt, Germany.

The Trinitatiskirche is a non-geosted brick hall church with a rectangular plan, its long walls divided by stepped buttresses between round-arched windows and topped by a brick frieze. A round stained-glass window sits in the choir area, and the slightly raised altar zone is framed by a round-arched triumphal arch. The massive three-storey tower stands crosswise to the nave, with three narrow sound openings on each long side and two on each short side; both tower and nave are covered by pitched roofs.

A wooden church once stood at this location until it burned down in 1690. The current brick building was constructed to replace it and officially opened its doors in 1901.

The name Trinitatiskirche was given on 28 January 1996, 95 years after the church was consecrated. The congregation was formed in 1899 from Langholt, Burlage and Klostermoor, and today has around 1,600 members. The church holds services and community events.

The church is not oriented to the east: the rectangular nave runs with its long sides flanked by stepped buttresses between the round-arched windows, and the three-storey tower stands crosswise to the nave. The tower's long sides each hold three narrow sound openings, its shorter sides two. The interior is plain, with the altar before the round-arched triumphal arch and the wooden pulpit to its right.

The organ was built in 1953 by Alfred Führer with nine stops on two manuals and a pedalboard. It stands in a plainly furnished interior, where the wooden pulpit is placed to the right of the altar before the triumphal arch.
