Considered on its own, the tree avenue on the Karmelenberg is already worth a trip. It is the oldest avenue of trees in Germany. It was created in 1662, when the Lady Chapel was also built. In total, it is 1.1 kilometres long. It originally consisted of 150 trees. Of the trees planted in 1662, there are still 46 copper beeches, 37 oaks, 16 winter lime trees, 6 horse chestnuts and a huge large-leaved lime tree. Because of its uniqueness, the tree avenue was declared a natural monument as early as 1939. A hike from the historic centre of the village to the Marienkapelle is a unique experience, also ideal as a "Sunday excursion". Translated with www.DeepL.com/Translator (free version)
