Stairway to heaven
A lot of treehouses have been built as a shelter from the jungle-animals. Nowadays, there are still tribes who built their home on the trees for this purpose, but in Europe and USA many treehouses have been built as a place to rest, far from the city and the classical house.
There are some treehouses that are easy to access and other like this one, that you have to make a commitment to reach it! For sure not a treehouse for everyone, but for sure for someone who wants to bring some time alone!
