This unusual designed building is known as The Dancing House and was designed in 1992 and completed in 1996. The house resembles a pair of dancers and was originally named Fred and Ginger after the famous dance couple Fred Astaire and Ginger Rogers.
It is now used as an office block but is not accessible to the general public except for the roof restaurant.
The photograph was taken from the end of the Jiráskův bridge, which had hollow tubes in two of its pillars, enabling the bridge to be destroyed if charges were set in them. The tubes lasted until World War II, when German soldiers filled them in over concerns that the Czech Resistance would blow up the bridge.
