Propsteikirche, Leipzig, Catholic parish church near Wilhelm-Leuschner-Platz, Leipzig, Germany.

Propsteikirche St. Trinitatis is a Catholic parish church built of light brown brick in large rectangular blocks, with a box-like main volume and horizontal bands of recessed dark windows. A 50 m bell tower with a clock and a dark bulbous dome topped by a cross rises behind the brick base. The complex is based on a triangle, with the church, chapel and sacristy in the east and a congregation hall, offices and priest apartments in the west.

The first Trinitatiskirche was built in 1847 on Rudolphstraße and became a provost church in 1923. Bombing in 1943 left only its outer walls and tower, and the ruin was blown up in 1954. The second church, built by the Bauakademie der DDR in a suburb, was consecrated in 1982 but soon showed structural damage. The current church, designed by Schulz und Schulz, was consecrated on 9 May 2015.

The name refers to the Holy Trinity, and this is the third Trinitatis church in Leipzig. The north window by Leipzig artist Falk Haberkorn shows Old and New Testament texts that read differently as daylight changes; the glass was made by the Derix company.

The complex sits at the southwestern corner of the Inner City Ring Road, at Nonnenmühlgasse 2 opposite the Neues Rathaus. The 50 m bell tower marks the western tip of the triangular layout, with the church, chapel and sacristy in the east and the parish hall and offices in the west.

A monumental window by Falk Haberkorn displays texts from both testaments that shift in appearance depending on the time of day. This artistic element connects the religious message with the changing light throughout the day.
