St. Claret-Ziegelhof, Catholic parish church in Donaustadt, Vienna, Austria.

St. Claret-Ziegelhof is a Catholic parish church with a square floor plan and distinctive roof windows that provide natural light to the interior. The building integrates a worship hall with community rooms under one unified structure.

The church was built in 1981 to a design by the IGIRIEN studio of architects Werner Appelt, Franz E. Kneissl and Elsa Prochazka, as a so-called church multipurpose hall. The parish began in 1975 when Father Erwin Honer started a Catholic community centre in the Ziegelhof housing estate. The Claretians run the parish, dedicated to their founder, Saint Anthony Mary Claret.

The church is dedicated to Saint Anthony Mary Claret, founder of the Claretians, who run the parish. The name also refers to the adjacent Ziegelhof housing estate. The building type, a church multipurpose hall, was first used in Donaustadt in 1977 and adapted here in 1981.

The church is located at Quadenstraße 53 in Vienna's 22nd district and is easily accessible by public transportation. Regular services take place, and visitors should check current opening times before planning a visit.

The church is part of a trio of similarly designed sacred buildings in the Donaustadt district, all built during the same period. This architectural grouping shows intentional planning in developing religious infrastructure for the growing neighborhood.
