The Federal Palace refers to the building in Bern housing the Swiss Federal Assembly (legislature) and the Federal Council (executive). It consists of a central assembly building and two wings (eastern and western) housing government departments and a library. The two chambers where the National Council and the Council of States meet are separated by the Hall of the Dome. The dome itself has an external height of 64 m, and an internal height of 33 m. The mosaic in the center represents the Federal coat of arms along with the Latin motto Unus pro omnibus, omnes pro uno (One for all, and all for one), surrounded by the coat of arms of the 22 cantons that existed in 1902.
