Sammallahdenmäki is a Bronze age burial site in Finland in Lappi municipality. It was designated by UNESCO as a World Heritage Site in 1999, and includes 36 granite burial cairns dating back more than 3,000 years, to 1,500 to 500 BC. It is located on a hill in a remote area off the road between Tampere and Rauma. Originally, it was near the coast of the Gulf of Bothnia, but the land has risen so it is now 15 kilometers from the sea.
