Bonn is dominated by the Rheinische Friedrich Wilhem University, with a student population of more than 24,000. The city has several beautiful churches, including the Kreuzbergkirche, Doppelkirche, and Das Bonner Münster Basilica, and other interesting buildings ranging from medieval to modern. Bonn also has many museums, including art museums, history museums, and a zoological museum. On nice days, visitors can enjoy spending a few hours in the Arboretum or Botanical Garden, or any of the other pleasant parks in Bonn. There is also an extinct volcano to climb on the border with Wachtberg and Rhineland-Palatinate. The city is small enough to explore on foot, but there is an excellent public transport system.
Despite these pleasant and worthwhile attractions, Bonn is most widely known as the birthplace of Ludwig van Beethoven, and there are many attractions in Bonn relating to the famous composer. The Beethoven House, located at Bonngasse 20 in the house he was born in, has the world's largest collection of Beethoven artefacts and memorabilia, including several of his pianos and a collection of busts. Nearby is the chamber music hall (Kammermusiksaal), where there are regular performances of Beethoven's works.
