Boglösa gĺrd 109, Brandskog. The "Brandskogship". The locality is situated at the edge of wood, at a wide sloping rock facing NE. The site is dominated by the huge ship figure, generally called "the Brandskogship", 4.2 m long. There are 6 paddlers in the ship, dressed in some kind of clothes, and a human figure under the ship, 1.1 m long, holding on to it or carrying it on the shoulder. The other 3 ship figures are 222 cm, 55 cm (totally carved out) and 39 cm long. The foot print is fragmentary.

The Uppland carvings are most north-easterly of the concentrations of south Scandinavian rock art tradition. The rock carvings of Uppland are generally dated to the middle and later part of the Bronze Age, c. 1200-500 BC. Occasionally, more absolute dating of single panels or figures can be made, based on typological or stylistic features of the image, and by comparisons with identifiable objects. Where a carving has the same object shown, or it is in the same style or has the same decoration as other objects dated to the Bronze Age from graves and hoards, then we can begin to apply some dating to the carvings. The size of the Brandskogship, the dressed paddlers and the human figure under the ship differ from the usual style and form of the Bronze Age carvings. The dating to the Bronze Age has therefore been questioned.
