Overview

Onsved Marker 3 is a megalithic long barrow of the Neolithic northern group of the Funnel Beaker culture, in Skuldelev parish, Frederikssund Municipality, Denmark. The catalogue gives a typological estimate of 3500 to 2800 BCE.

The rectangular mound, oriented north to south, contains three chambers, all classed as early dolmens (Urdolmen). Older and newer surveys give slightly different dimensions for the mound.

Description

Sources for this section

The mound is rectangular and oriented north to south. The 1873 survey gives a length of 40 m and a width of 10 m. The 1942 report gives a length of only 30 m and a width of between 10 m and 11 m. The mound is 1.6 m high.

In 1873, 55 stones of the kerb survived. In 1942 only 37 remained: 16 on the western long side, 19 on the eastern long side and two on the southern end. The stones at the ends are, or were, larger than those along the long sides.

The first chamber lies 14 m from the southern end of the mound. It is oriented west-north-west to east-south-east and has a slightly trapezoidal plan, 2.1 m long and 0.7 m wide in the east and 0.9 m wide in the west. It has three wall stones, its west side is open, and the capstone is missing.

The middle chamber lies 20 m from the southern end. It is oriented north to south, with a rectangular plan 1.6 m long and 0.7 m wide. It consists of one wall stone on each side, one of which is split. Its capstone is also missing.

The third chamber lies about 29 m from the southern end. It is oriented east to west and has a rectangular plan; no dimensions are recorded. It has three wall stones, with a threshold stone at the open east side, and a capstone rests on the wall stones. Around this chamber, rolled stones and burnt flint were observed.
