Berlin's tiny medieval heart is the Nikolai Quarter, whose only truly medieval-looking building today is the Nikolaikirche. The church dates to 1230 and was rebuilt along with the entire quarter in the 1980s to mark Berlin's 750th birthday in the area in which the fishermen's settlement first began. No one was trying to outdo Walt Disney here, and many of the buildings have the simple, concrete facades that the GDR government could afford. The small shops in the area mostly deal in toys and souvenirs and tourists gladly fill the sunny tables at the restaurants that face the river. On Rathausstraße, there's a row of restaurants that flaunt old-fashioned Berlin cuisine and atmosphere. Other rebuilt historic buildings in the area date to the 1700s, such as the Ephraim-Palais and Knoblauchhaus. Both have changing exhibits related to Berlin.
