Two bronze age (from 1500 BC to 500 BC in Finland) burial cairns in Sepänmäki, Eura, Finland. Southern cairn width is 12 meters and height 3 meters. Northern cairn width is 13,5 meters and length 8 meters. There is also a unfinished stone grave between the cairns. Maybe there was a plan to build a third cairn between the two. The other two cairns may also include similar grave structure.
