Main image

Sammallahdenmäki is a Bronze Age burial landscape in Satakunta, western Finland, recognized for a large collection of stone burial cairns. The site is notable for its coherence and state of preservation across a rocky ridge.

The complex contains dozens of stone cairns and burial monuments dating to the Nordic Bronze Age, roughly the second to first millennium BCE. The cairns vary in form and size and are concentrated along a prominent ridge, creating a visible funerary landscape.

Archaeological study over the 19th and 20th centuries documented the cairns and led to national protection; the site was inscribed on the UNESCO World Heritage List in 1999 because it exemplifies Bronze Age funerary practices in the Baltic region.

Sammallahdenmäki sits on a rocky promontory in the municipality of Rauma in Satakunta, overlooking forested coastal terrain of western Finland and accessible by local roads from nearby towns.

  • UNESCO listing: Inscribed as a UNESCO World Heritage Site in 1999 for its well-preserved Bronze Age burial cairn landscape.
