St. Nicholas' Church (German: St. Nikolaikirche) in Potsdam is an Evangelical church on the Alter Markt ("Old Market Square") in Potsdam. The central plan building in the Classicist style and dedicated to Saint Nicholas was built to plans by Karl Friedrich Schinkel in the years 1830 to 1837. The tambour of the 77 metre high church that towers above the roofs of the city was built later, from 1843 to 1850. Its construction was taken over by Ludwig Persius and, from 1845, Friedrich August Stüler.Towards the end of the Second World War the church was hit during the air raid on Potsdam and subsequently badly damaged by Soviet artillery fire. After many years of rebuilding the church was re-consecrated in 1981 by the Evangelical Parish of St. Nicholas, Potsdam, and, today, is open to visitors. In addition to the normal church services, concert events are also held in the church.
