Metsänkylän Kartano - Metsäkylä Manor. Actually you should talk about Metsäkylä Cowhouse nowadays, though that name is not giving you a correct picture even. They sell old building materials and keep a cafe. Open on Sundays. Absolutely worth visiting. Check: http://www.metsankylannavetta.fi/
The Snow Castle of Kemi has been operating annually since 1996 and each year the architecture is varied. The castle has boasted 20m high towers, 1,000m long walls and has been built up to three stories. This may sound normal until you know that it is completely built of snow and ice. Get there before it melts.
