Nikolaiviertel, Medieval district in Mitte, Berlin, Germany.

Nikolaiviertel is a reconstructed quarter in Berlin-Mitte, built 1980–1987 under architect Günter Stahn around the late-Romanesque Nikolaikirche, which has a neo-Gothic twin-tower facade added in the 1870s. The layout follows the medieval street plan, mixing recreated burgher houses with concrete Plattenbau blocks. The Spree borders it to the east and south, and the waterfront row includes buildings with red tiled gable roofs and ground-floor signs such as "Restaurant" and "LA RIVA".

The district was founded around 1200 as Berlin's original settlement and served as the city's center for centuries. Following severe damage in World War II, it underwent major reconstruction in 1987 to commemorate Berlin's 750th anniversary.

The Knoblauchhaus museum here displays how wealthy Berlin families lived during the 1800s, with period furniture and everyday objects on view. You can see the Biedermeier style that shaped domestic life in that era.

The area is easily walkable, with narrow lanes that invite leisurely exploration on foot. You can eat traditional German food at local restaurants and browse handmade crafts and souvenirs in shops scattered throughout.

The Eiergasse, at 16 metres, is Berlin-Mitte's shortest drivable street, and the quarter's lanes were laid out on an almost medieval ground plan. The Ephraim-Palais was rebuilt between 1983 and 1987 about 12 metres from its original site, after West Berlin handed the stored Rococo facade parts to East Berlin's magistrate in 1982.
