Jerichow is home of Jerichow Abbey, the former Premonstratensianconvent which was founded as early as 1144. In 1148 the construction of the convent church of St Mary and St Nicholas in a late romanesque style started. This makes it one of the oldest remaining brick buildings in Northern Germany and, through its artistic perfection, highly influential on the brick architecture in the Margraviate of Brandenburg. The Abbey was shut down as such in the course of the Protestant Reformation in the 16th century and the buildings have been used for various purposes since that time. Major repairs were made in the late 17th and the mid 19th century. The buildings were damaged by American artillery during the last days of World War II and by a major fire in 1946. East Germany organized several rounds of provisional repairs in the 1950s and 1980s, but considerable war damage remained unfixed, and several buildings were near collapse in 1998, so that the Abbey had to be closed to the public. After this made the Abbey's problems obvious and put its continued existence in danger, a serious effort to repair the war damage materialized quickly and with much popular support. The buildings were reopened to the public in 1999. They were fully restored in the following years and can be visited today.
