[3][1] The realisation of plans drawn up in the late 1930s to build a new church was frustrated by the outbreak of World War II.
[1] In the first weeks after the end of the war, in May 1945, a garage in the Koschatgasse served as a provisional venue for services; the City of Vienna earmarked a section of the gardens in the Glanzinggasse in July of the same year for the construction of a church.
This structure was sanctified on 29 September 1946 and given the title Mariä Verkündigung (Annunciation of Mary), but several years passed before a proper church could be erected.
[2] In 1957, a section of the garden belonging to the University of Natural Resources and Applied Life Sciences Vienna in the Krottenbachstraße, Obersievering, was purchased, where the parish church Verkündigung des Herren (Annunciation of the Lord), designed by the architect Josef Lackner [de],[2][1] was built between 1969 and 1970.
[5][2] The wooden structure in the Glanzinggasse was taken down in 1972 but continued to serve as a provisional church in the settlement Am Biberhaufen in Donaustadt.
