Rauma

The wooden city center of Old Rauma is an UNESCO World Heritage site and the largest unified historical wooden town in the Nordic countries. Most buildings date back to the 18th century. It is also a fully functioning downtown shopping district with many boutiques, cafes and shops to interest visitors.

For history and archaeology buffs, the bronze age burial site of Sammallahdenmäki is our second UNESCO World Heritage site and also just on the outskirts of town.

Here is a list of various museums, landmarks and other points of interest in and around town: http://www.rauma.fi/english/sights.htm
