Sammallahdenmäki is a Bronze Age burial site in the village of Kivikylä, well signposted off Highway 12 between Rauma and Tampere. While a UNESCO World Heritage Site of great archaeological significance, it's not all that much to look at, being composed of just 36 piles of stone of varying shapes and sizes. Guided tours starting from the parking lot are available Mon-Fri in the summer peak season (June-August) for a token €2/person.
