The Old Market Square (German: Alter Markt) is a centrally located square in downtown Potsdam which forms the historical centre of the city. The square consists of the area around St. Nicholas' Church. Today the term refers in particular to the area directly in front of the church. It is bordered by several prestigious historical buildings. The square has been the site of much architectural reconstruction work in recent years which has restored much historic building fabric that was lost in World War II.
