We rented the top house during our stay in Port Leucate, France which had good views of the local area. Can't remember how we got up to the top of the tree house, must be because of the consumption of wine.
When i first saw one of these plants I couldn't see the bottom of it & I thought it was an exotic tree. It is, I was told, a cactus plant - an aloe vera. Seen in France [Port Leucate]
