No. 1 Unter den Linden is the first building at the eastern end of the Unter den Linden in Berlin, Germany, and is of national architectural and historic importance.
It is a museum which has been decorated and furnished just as it might have been during the period 1776-1796. The rooms feature historic furniture, pictures and objects that reveal what life was like for Berlin’s fashionable residents – both upstairs and downstairs. The museum is a charity.
