Sammallahdenmäki

Sammallahdenmäki is a Bronze Age burial site in Finland in Rauma, in the region of Satakunta. The site includes 33 granite burial cairns dating back more than 3,000 years, to 1500 to 500 BC. Sammallahdenmäki is one of the largest, most complete, and most important Bronze Age sites in Fennoscandia, and was designated by UNESCO as a World Heritage Site in 1999.

== Description == The burial site is located on a long ridge in a remote area off the road to Tampere from Rauma. The 33 burial cairns making up the site are arranged into distinct clusters along the crest of the ridge. Each cairn was constructed from granite boulders quarried from the cliff face below the ridge or collected on site, in typical Bronze Age fashion. Of the 33 cairns, 28 are dated to the early Bronze Age, and the rest to the early Iron Age. Several different shapes and sizes of these cairns exist at the site. Two unusual cairns are the Huilun pitkä raunio ("long ruin of Huilu"), which is surrounded by an ancient stone wall, and the Kirkonlaattia ("Church Floor"), an unusual rectangular cairn covering 16 x 19 metres with a flat top. The "Church Floor" cairn is the only one of its type found in Scandinavia.
