The barrow of Sagaholm. Nothing remains of the once so magnificent barrow, written records speak about a diameter of c. 22 m and about 2.5 m high, even when severely damaged. The archaeological investigation showed that the barrow consisted of turf from sandy soil, and the contours from decomposed turf were visible in the sand under the barrow. Along the edge of the barrow there was a stratified mixed layer of earth and stones of varying sizes, 0.05-0.6 m. Under this layer there were 2 rows of kerb-stones. The inner kerb-stones consisted of slabs of sandstone, placed edgeways leaning, turned outside. The slabs were cut and had been dug into the ground, 0.25 - 0.85 m wide and 0.4 - 1 m high. On the outer sides of the slabs rock carvings were depicted. There are 18 remaining slabs with carvings, arranged in a certain way. There are a number of ship figures with totally carved out hulls, some with crew lines placed in pairs on the gunwale. There are a number of animals, the majority depicting stylised horses, and also other kinds of animals, possibly a buck. On slab no 13, a previously not known horse figure was discovered in 1997, during a re-documentation of the slabs (Goldhahn 1999:59). There is also an unusual scene depicted, showing a human figure having sexual intercourse with an animal. This motif is known from Bohuslän (Kallsängen) and also from Valcamonica. Most of the animals seem to be horses. Another scene is showing a human figure equipped with bow and arrow, and an animal of some kind. The motif is quite unusual, but similar scenes are known from Bohuslän, and also Östergötland. The most common technique used is pecking technique, but also carved with a tool made of metal or flint. Some of the slabs have been grinded after the pecking.

The barrow of Sagaholm belongs to the Early Bronze Age, and have been C-14 dated to c. 1450 BC. The find is of vital importance for the dating of the South Scandinavian rock carvings.
