Kuninkaanhauta (Finnish for Royal Tomb) is a cairn (a type of burial mound) in Finland. It is the largest burial mound of its kind and is located about 50 km north of Turku. The burial mound is oval in shape and has a diameter of between 37 and 45 meters.
The hill is 3.6 meters high. Calculations show that the volume of the burial mound was 2000 cubic meters. This amounts to about 250,000 stones of 20 cm. in section.
The hill dates back to the Finnish Bronze Age (1500–500 BCE) and has never been excavated.
In the vicinity of the burial mound, studies were conducted between 1987 and 1988. Circular structures, probably remains of huts, and firepits were found. Shards of ceramics and animal bones were also found. The residence is dated to 520 BCE.
