The Füssen Tree Garden is a public park located above Füssen on a hill and adjacent to the castle hill of the High Castle. Originally, the tree garden formed a unit with the castle hill on which the High Castle is enthroned. The site where the park is located today has a proven Roman history. It may have been the site of Damasia, the capital of the Likatians, which was destroyed by the Romans. A fort stood on the neighbouring castle hill in the late Roman imperial period. The Via Claudia Augusta, which probably led past the Baumgarten or through it to Bad Faulenbach, was also laid out here at this time.
