The poet Friedrich Hölderlin (born in 1770) lived here from 1807 until his death in 1843. He was mentally ill and the family of carpenter Zimmer accommodated him in this building. Today the Hölderlin Tower is a literary memorial place and museum.
In the late 18th century the tower was built on the pedestal of the inner ring wall. According to the findings of square stones at Neckarbrücke the wall dates back to the 13th century.
