Lauffen am Neckar
In 1914, two districts (Lauffen-Stadt and Lauffen-Dorf) were merged to create the new town of Lauffen am Neckar. The new town council marked the occasion by planting a lime tree in the terraced garden in front of the Pfalzgrafenburg castle. This tree stands opposite another lime at the Regiswindis Church on the other bank, the two trees thus symbolising unity.
