Snottsta and Vreta stones, Viking runestones in Uppland, Sweden

The Snottsta and Vreta stones are four runic monuments in Uppland: U 329 and U 330 stand at Snottsta, U 331 is a flat rock there, and U 332 at Vreta is lost but known from an 18th-century drawing. Carved in style Pr3 around 1050–1080, they record Inga's inheritance of Snottsta after her husband Ragnfast.

The four stones were carved in runestone style Pr3, dated 1050–1080, and form part of the family story of Gerlög and Inga. U 329, U 330 and U 331 were carved first, then U 20/21, and last Gerlög's Hillersjö stone (U 29). U 332, the Vreta stone, has disappeared; its inscription is known from an 18th-century drawing.

The inscriptions tell stories of Gerlög and Inga, showing how women owned and controlled property during the Viking Age. These details carved in stone reveal the role women held in their family and community.

These stones are best visited in spring and summer when the paths are accessible and weather is stable. Reaching the homesteads from Stockholm requires combining train and bus transportation to this remote location.

U 332, the Vreta stone, has disappeared; its inscription survives only through an 18th-century drawing. It records that Inga raised a staff (staf) as well as stones in memory of her husband Ragnfast, a rare monument type also known from Sö 196 and Vs 1.
