Bielefeld is an independent city that is the largest city of
the Ostwestfalen-Lippe Region. The centre of Bielefeld is situated on the eastern side of the Teutoburg
Forest, but the modern city incorporates boroughs on the opposite side and on
Bielefeld has a small airstrip, Flugplatz Bielefeld, in the Senne district but
is mainly served by the two larger airports nearby, Paderborn Lippstadt Airport
and Münster Osnabrück International Airport.
Sparrenburg Castle is the most famous landmark. It was built between 1240 and
1250 by Count Ludwig von Ravensberg. The 37 m high tower and the catacombs of
the castle are open to the public. The oldest city church is Altstädter
Nicolaikirche. It is a Gothic hall church with a height of 81.5 m. It was
founded in 1236 by the Bishop of Paderborn, and enlarged at the beginning of the
14th century. The church was damaged in World War II and later rebuilt. Three
times a day, a carillon can be heard. The most valuable treasure of this church
is a carved altar from Antwerp, decorated with 250 figures. A small museum
housed within illustrates the history of the church up to World War II.
