On the 7th May 1945, the city hall was shot at and set on fire. The Eastern and the Northern wing opposite the Týn temple were completely destroyed, and the tower with the astronomical clock (Orloj) and the chapel were badly damaged. On the ground floor, the archive of the Capital City of Prague was destroyed, together with a library and valuable collections. To commemorate the 30th anniversary of the liberation, the collapsed part of the building was repaired, preserved, and the blank window was furnished with a grille and memorial plaques. The authors of these modifications were ing. arch. J. Koreček and academic sculptor J. O. Lankáš. There were several attempts to open tenders for completing the destroyed parts of the building, yet they were never realized. Surprisingly, the fire did not destroy the elevator within the city hall’s tower, which was made in 1927 and it was a rare piece, which was in operation for a long time. It was taken over by the National Technical Museum and added in its collections, and in 2000 a new elevator with a barrier-free construction was finally put into operation within the main staircase and in the city hall’s tower.Throughout its existence, the city hall passed all the architectural periods. Today, it is made up of a block of houses from different eras, which were gradually added to it. The base is formed by Romanic houses, the remains of which are located in the basements.
