Sankt Theresia, Modern parish church in Linz, Austria

Sankt Theresia is a Roman Catholic parish church in the Keferfeld area of Linz, built 1959–1962 to a design by Rudolf Schwarz with structural planning by Hans Aigner. A freestanding tower stands before the church, whose plan forms a long oval with two corners. The walls are a concrete skeleton infilled with brick and gridded with windows, and the flat roof is ribbed with concrete beams.

A branch church built in 1930 for the Leonding mother parish was destroyed by bombs on 27 December 1944; a temporary barrack church followed on the same foundation until 1946. Pastor Josef Zauner engaged architect Rudolf Schwarz for the new building, erected 1959 to 1962 with structural planning by Hans Aigner. Bishop Franz Zauner consecrated it on 7 October 1962.

The church is dedicated to Saint Thérèse of Lisieux, and the weekday chapel is clad in Mauthausen granite as a memorial to the Mauthausen concentration camp, recalling the wartime destruction of the earlier church. The oval plan places the baptismal font in a bay by the entrance and the altar in the rear bay, which opens into a side bay holding the organ.

Visitors can find the church at Losensteinerstraße 6 and are welcome to enter during opening hours. Check ahead for special events like Advent celebrations or children's services to plan your visit.

The weekday chapel is clad in Mauthausen granite, a deliberate choice to commemorate the former church destroyed in the war and to serve as a memorial to the Mauthausen concentration camp.
