Gamla Turingevägen Inscriptions, Swedish runic inscriptions

The Holmfast Inscriptions (Sö 311, Sö 312, Sö 313) are carved on a single immovable rock outcrop beside Holmfastvägen in Södertälje. Sö 311 is a damaged serpent-band inscription 1.2 m high in Urnes style Pr3; Sö 312 is 1.5 m high, encircles a Christian cross in style Pr4, and ends with the runemaster Östen's signature; Sö 313 is purely ornamental, showing a lean wolf with hanging tongue, rune snakes and a braided ring cross.

The three carvings on one rock face date to 1050–1080 and were signed by the rune master Östen. Sö 312 records that Holmfast had a road cleared and a bridge built in memory of his father Gamal, who lived in Näsby, about three kilometres west by Lake Måsnaren. Sö 311 commemorates Holmfast's mother Ingegärd. The road was reinforced with stone or timber where the ground was sunken, and today's Holmfastvägen still follows its route.

The carvings are known as Holmfastristningen after Holmfast, who had the road cleared and a bridge built in memory of his father Gamal, who lived in Näsby, and his mother Ingegärd. The text ends with the prayer "God help his spirit", and the ring cross shows the family was Christian.

The stones are located on a rock face directly beside the old road and are easy to spot as you pass by. Visit during daylight hours to clearly see the fine carvings and the animal-shaped patterns etched into the surface.

Sö 312 is the only surviving inscription signed by Östen: he simply added his name at the end of the text, without a verb such as "carved". Two other Urnes-style carvings, Sö 338 at Turinge and Sö 344 at Kiholm, are attributed to him on stylistic grounds alone.
