The building and its surroundings were seriously damaged in the siege of Budapest in 1944-45. A bomb hit the western side of the building, the roof, the spire and the obelisk of the pediment were destroyed, the liturgical furnishings and the altars were extensively damaged or lost. Repair work began in June 1945, and the church became functional again by the autumn, although the interior renovations went on in the following years. The renovation was still funded by the Municipal Authority of Budapest that remained the patron of the parish until 1950 when the right of patronage ceased to exist.
