The Asian or Oriental plane (in Dutch: plataan) in the Heerlijkheid Hemmen is popular with children as a hollow 'kabouterboom'. (leprechaun-tree?)
Most people, children and adults, from the environment know this tree.
I like the opening in the tree trunk. saw something like that once with a real wooden made door in front which you could open and put something inside. I know I posted it here but don't know where and when after 8 years.
