Most lovely walk in a quiet place called Mustjala (Blackleg) in Saaremaa.
I've seen such oddity also in Otepää.
Some more photos of other buildings too.
There was a nice cafeteria+handcraft shop inside this house, we ate lunch here. I am still eating that incredibly spicy chilli-mustard that I bought here (Mustjala Mustard). Even tasting it a bit in the shop put my nose running.
