Good morning and thank you so much, @wwwiebe 🙂
In Summer the sun rises about behind the boat house and I have seen some really nice photos from it :)
I have found a Wikipedia article about bath houses: https://en.wikipedia.org/wiki/Public_bathing
Nowadays the buildings are still there sometimes, but it is all just like on a normal beach with areas where people can sunbathe, children can play and you can go swimming.
This bath house belongs to the villa which would be on the left side. The boat has it's garage on the first floor and the people can enjoy nice sunny days on the second floor and go downstairs for a swim.
I hope my explanations are somehow understandable, but otherwise the Wikipedia article might help better 😉
To give a !DERANGED and a !BEER is an easy and simple way for me to say thank you for being nice, and giving an additional !MARLIANS or !COFFEEA means I thank you even more 😉
