A wide building gap gaps on the northern edge of the Várhegy, the narrow mountain range parallel to the Danube, on which the Budapest castle is enthroned. To the right of the gap: The massive building of the Hungarian State Archives, a historical building from 1923. Left: A narrow staircase made of concrete and glass, which the associated house is missing. It was part of the archive expansion construction from the 1970s, which has now been demolished.
