And now my memory for Finish names deserts me. Woke up early(ish) and took the train somewhere, where girlfriend told me the had a castle. She was right! For those handy with google, they had an artillery museum as well. Visited the castle and found out that it probably is one of the best heated castles in all of the world. Walked around the town with the missing name for a while and eventually took the train back home for food and staying in.
