The iconic blue Moomin House can be found inside the Moomin World Theme Park, which is based on the books by Tove Jansson. It's located on the island of Kailo beside the old town of Naantali in Finland.
Moomin World isn't a traditional amusement park, as it does not have rides but there are many activities, performances and fantasy paths for children.
The Moomin House is the main attraction and tourists can visit all five storeys that house Moominmama's Kitchen and more.
