Schloss Benrath (Benrath Palace) was built as a pleasure and hunting palace for the Elector Carl Theodor. Today, the ensemble in its artistic unity of buildings, interior and gardens, 60 hectares in all, is considered one of Europe’s rare complete works of art of the late baroque period. The main palace building (corps de logis), with its furniture, porcelain, paintings, etc., gives an impression of court life in the second half of the 18th century. The eastern wing houses the “Museum für Europäische Gartenkunst” (Museum of European Garden Art) and the western wing the “Museum für Naturkunde” (Museum of Natural Sciences).

The amazing Mapu’a Vaea blowholes extend for 5 kilometres along the south shore on Tongatapu. Their name means "Chief's Whistles", and you can see the water forced through the natural vents in the coral limestone cliffs sometimes up to 30 metres in height.

Tonhalle, home to the 'Düsseldorfer Symphoniker', also hosts many international guest performances. The city's orchestra consists of 130 musicians, and with its many tours in this country and abroad has made an excellent name for itself far beyond the city borders.
