Strange structure on the beach - Outo rakennelma rannalla

I have heard that there is going to be hot tub on top of that willow covered cone. Background is the restaurant building which was empty for a long time but now it has been restored and will be opened on May Day.

On kuulemma kylpypikari tämä. Taustalla oleva ravintolarakennus oli pitkään tyhjillään mutta nyt se on kunnostettu ja avataan vappuna.
