St Nicholas, Church building in Jüterbog, Germany.

St Nicholas is a Brick Gothic hall church 71 metres long and 23 metres wide, the largest sacred building in the Jüterbog area. Its three-aisled nave of five bays and a choir is mostly red brick with patches of field stone, while the two west towers are field stone with sandstone details. The towers differ: the north has a Renaissance octagon and canopy finished in 1617, the south a stone pointed spire.

St. Nikolai was first mentioned in 1307 and probably consecrated in 1488, as recorded in an inscription in the council pew. The nave was extended by one bay at the end of the 14th century, and the south annex followed in the early 15th century. The two field-stone towers were built separately and finished around 1500; the north tower's Renaissance hood was completed in 1617. Renovations followed in 1821–1824, 1877 and 1934–1936.

The patron saint is Nicholas of Myra, and a near life-size statue of him stands above the Gothic sandstone portal between the towers. A memorial plaque recalls Thomas Müntzer, who preached here at Easter 1519; his radical ideas soon clashed with both the Catholic Church and Luther. A chapel keeps a rare surviving indulgence chest linked to Johann Tetzel.

The church stands between Nikolaikirchstraße and Große Straße, towering over Jüterbog's old town. A climb of 217 steps leads to the viewing platform of the south tower at the height of the arch bridge linking the two towers. The church is maintained as an open church.

The small positive organ of 1657, built by Christoph Werner with five stops, is the oldest surviving organ in Brandenburg. The north tower once housed a tower keeper; after World War II the Junge Gemeinde used the flat, and it has stood empty since the 1960s renovation.
