St. Nicolai, Romanesque church in Burg bei Magdeburg, Germany.

St. Nicolai is a late 12th-century Romanesque pillar basilica in Burg bei Magdeburg, built of carefully hewn and jointed granite blocks. Its wide transept has two semicircular side apses, and the square main choir ends in a rounded apse. Inside, the nave arcades open onto large wall surfaces, and the west end rises as a twin-tower block with slender spires.

St. Nicolai was first mentioned in 1186 as a branch church of the Upper Church of Our Lady and was built in the late 12th century as a Romanesque pillar basilica of carefully hewn granite blocks. The westwork with its two towers followed in the same century. In 1606 the original flat ceiling was replaced by a wooden barrel vault, and the western pair of arcades was walled up. After neglect between 1974 and 1985, the church was restored from 1985 to 1990.

The church sits on Lutherplatz and today serves as an evangelical house of worship where locals and visitors gather. The square itself has become a focal point of public life, with the building's presence shaping how people experience this part of the city.

The church is centrally located and easily reached on foot, especially when visiting Lutherplatz nearby. Visitors should remember it remains an active place of worship, so visits work best outside of service times.

The Romanesque font from the second half of the 12th century was destroyed in the 19th century; in 2001 it was reconstructed using original fragments of the bowl. The 1607 sandstone pulpit by Michael Spieß is borne by a full sculpture of Moses, and its alabaster reliefs show the donors kneeling at the Crucifixion.
