Sö 298 is the Rundata catalog number for a Viking Age memorial runestone located in Uringe Malm, which is about four kilometers west of Väländan, Stockholm County, Sweden, in the historic province of Södermanland.
This runestone, which is made of granite and is 2.3 meters in height, consists of runic text carved on a serpent that surrounds a Christian cross.
This runestone style is characterized by slim and stylized animals that are interwoven into tight patterns.
The animal heads are typically seen in profile with slender almond-shaped eyes and upwardly curled appendages on the noses and the necks.
In this inscription, Halvdan used a + as a punctuation mark between each word of the runic text.
