Slagsta, Botkyrka parish. Situated on a smooth, steep rock, dark in colour (amphibolit) close to road and Fittja subway station. The ship figures are double-lined with upturned prows and extended and upturned keel-line, strict in style. No crew-lines. Some of the ship figures are fragmentary or unfinished. The horses are very elegant in style, with curved bodies and distinctly carved lines. The three horses are placed over one of the fragmentary or unfinished ship figures. Cup marks are distributed over the whole area, some arranged in groupings concentrated to the base of the rock.

The rock carvings of Södermanland are generally dated to the middle and later part of the Bronze Age, c. 1200-500 BC, and belong to the same tradition as major part of the South Scandinavian rock carvings. 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 carvings in Södermanland might belong to the Late Bronze Age, which seem an expanding phase for among other things farming and stock-raising with a growing need for cultic places.
