Impressive tree. Translation of the information board: "You probably still have a long way to go before you reach the large step ahead. This is an ash tree that we believe is at least 100 years old. Large and old ash trees are a rare sight in Denmark because ash disease is caused by a fungus that causes the upper branches of the trees to die and the leaves to fall off. Unfortunately, many ash trees and stands are affected by this fungus. Fortunately, this tree does not appear to be affected by the fungus. In 2019, this tree was designated a "Tree of Life," which means it is protected and may not be felled for production. We would therefore like to ask you to help us protect the ash tree by not stepping on the fence, climbing the tree, or poking at it. This way, the ash tree will hopefully remain standing for many years to come and bring joy to many people.

The Kalø Long Barrow II is an ancient Neolithic burial mound. But it isn't just a pile of stones; it's a testament to millennia of human presence in this region. Situated on a small hillock, this megalithic monument standing before you is a structure that dates back over 5,000 years, offering a tangible connection to Denmark's first farmers and their burial rituals.
