A relic of a cemetery dissolved in 1870 is the grave monument of the Alemannic poet and prelate Johann Peter Hebel, who died in Schwetzingen in 1826. His portrait by Heinz Friedrich can be found in a mural on an adjacent building. Motif benches, information pillars, a wind chime and tree plantings refer to Schwetzingen's twin towns and thus define the place as a place of friendship.
