Siegen

It is run by Harold Krämer. According to the 2000 Guinness Book of Records, the 27-m² museum is the smallest public museum in the world devoted to the four Liverpudlian musicians. The collection consists of more than 17,000 sound storage media, souvenirs, film posters, autographs and quite a few other things.

The castle on the Siegberg was first mentioned in a document in 1259 and was the family seat of the House of Nassau. Since 1905, the Siegerlandmuseum has been here. Alongside regional exhibits – among them an artificial demonstration mine – are many paintings. The centrepiece of this collection is made up of works by the man who is arguably the best known son of the city, Peter Paul Rubens. There is also quite a comprehensive collection of portraits of members of the Houses of Nassau and Orange. The top floor is devoted to 19th-century home décor. A kitchen from the Siegerland, a bedroom and many pieces of furniture from the Biedermeier era give one an impression of life in the region in bygone days.

Late in the 17th century, the Lower Stately Home came into being in its current form, somewhat like an open rectangle. The Evangelical line of the House of Nassau-Siegen resided here. Also belonging to the Schloss is the "Dicker Turm", or "Fat Tower" with a carillon. In 1959, the then town of Siegen built a memorial for victims of war and tyranny. Inside the Schloss is also found the crypt of the Evangelical branch of the Nassau princely house. Today, the Schloss serves as a campus for the faculty of economics of the University of Siegen.

The dating from the 11th century and the Nikolaikirche at the marketplace with its unusual eight-sided shape and its golden Krönchen ("coronet") – the city's landmark – on the church tower, which is a prominent feature of Siegen's skyline (Siegen is sometimes called Krönchenstadt for this unusual feature).

It was built by the Jesuits between 1702 and 1729.

Protected gasholder.In the southwest of the city core, at the foot of the Ziegenberg, is a spherical gasholder, or gasometer, which is protected by law as a monument. It is one of the oldest spherical gasholders still preserved. Another peculiarity is its riveted casing. Only three other such gasholders are known to exist worldwide (all in Germany, in Schwerte, Offenburg and Bielefeld). The holder had to be moved a few metres owing to construction on the municipal Autobahn, the Hüttentalstraße, and in the residential area of Ziegenberg, and it now forms the symbolic sun as part of a scale model of the planets above the gasholder.

It is a slag heap of the former Bremer Hütte, which was artificially filled in from 1900. Unofficially, the slag heap is considered the highest "mountain" in Siegen and a landmark of Geisweid. Please do not enter the actual area of the slag heap as there were numerous cases of accidents and even some rescue operations.
