Herz-Jesu-Kirche, Romanesque Revival church in Landstraße, Vienna, Austria

Herz-Jesu-Kirche is a neo-Romanesque basilica built from 1904 to 1906 to designs by Gustav von Neumann, with a tower facade facing Landstraßer Hauptstraße. The three-aisled church has a 39-metre length, a 10-metre-wide central nave, 5-metre side aisles and a 21-metre vault height. Its tower above the main portal now stands 65 metres high after war damage and the 1947/48 restoration.

The church was built from 1904 to 1906 to designs by Gustav von Neumann as a neo-Romanesque basilica with a tower facade facing the Landstraßer Hauptstraße. The foundation stone was laid on 8 May 1904, after the site was bought in 1903, and auxiliary bishop Godfried Marschall consecrated the church on 30 September 1906. The interior was finished only in 1922–1925 by the painter Franz Zimmermann and the ornament painter Hans Jakubetz. At the end of the Second World War the spire was shot off; after repair in 1947/1948 the tower stood 65 metres, seven metres lower than before.

The church belongs to the convent and hospital of the Dienerinnen zum Heiligsten Herzen Jesu, whose founder Peter Viktor Braun gave his name to the square in front, renamed Viktor-Braun-Platz in 2011. It is a filial church of the Rennweg parish, and the interior paintings were completed only in 1922–1925 by Franz Zimmermann and Hans Jakubetz.

The building is easily accessible in the Landstraße and open to visitors during set hours, welcoming both worshippers and those interested in architecture. It is helpful to check in advance when services or special events take place, as visiting hours may vary.

The tower over the main portal was hit at the end of the Second World War; after repairs in 1947/1948 it stood 65 metres tall, seven metres shorter than before. The church is a branch of the Rennweg parish and belongs to the convent of the Servants of the Most Sacred Heart of Jesus at Landstraßer Hauptstraße 137.
