During the late XIX century the Ottoman empire was trying to catch up with the West. Thus, the administration moved to a new palace, built with Baroque, Rococo and Neoclassical influences. The focus of the museum is on the lifestyle of the ruling family. Very interesting furniture, paintings and decorations.
