Tübingen is a traditional university town in central Baden-Württemberg, Germany. It is situated 30 km (19 mi) south of the state capital, Stuttgart, on a ridge between the Neckar and Ammer rivers.
In central Tübingen, the Neckar river divides briefly into two streams, forming the elongated Neckarinsel (Neckar Island), famous for its Platanenallee with high plane trees, some of which are more than 200 years old. Pedestrians can reach the island via stairs on the narrow ends leading down from two bridges spanning the Neckar. During the summer, the Neckarinsel is occasionally the venue for concerts, plays and literary readings. The row of historical houses across one side of the elongated Neckarinsel is called theNeckarfront and includes the house with adjoining tower where poet Friedrich Hölderlin stayed for the last 36 years of his life as he struggled with mental instability.
