The immaculately-looking white neoclassical palace on the Spreeweg, just off the Tiergarten’s northwestern corner is the official residence of the German President. The palace was erected in 1786 as a private residence for Friedrich the Great’s youngest brother Prince Ferdinand of Prussia as three-winged palace ideally situated on the Tiergarten hunting grounds. It was designed by architect Philipp Daniel Boumann. Over the centuries it became a school under Kaiser Wilhelm II (1888 – 1918) – the last German Kaiser – and a Reich guesthouse in 1939. The round arched windows of the side wings were converted from the original side entrances. The present building is the 1959 reconstructed version and only one room the Oval Saal (Oval Office) from Carl Gotthard Langhans is original. The President’s offices are located in the new building, the Bundespräsidialamt, south of the Palace, a contrasting glass and black granite edifice under heavy guard.References:
Frösöstenen is the northern-most raised runestone in the world and Jämtland's only runestone. It originally stood at the tip of ferry terminal on the sound between the island of Frösön and Östersund. The stone dates to between 1030 and 1050. It has now been relocated to the lawn in front of the local county seat due to the construction of a new bridge, between 1969 and 1971, on the original site.
Frösö runestone inscription means: Austmaðr, Guðfastr's son, had this stone raised and this bridge built and Christianized Jämtland. Ásbjörn built the bridge. Trjónn and Steinn carved these runes.
