This runestone, listed as U 13 in Rundata, crowns the barrow of Björn Ironside in Uppland, Sweden. The stone is a fragment; broken pieces of the stone lie next to it.

A transliteration of the damaged runic inscription is:

... ...[r]kutr þaiʀ... / ... atu ' ok| |ku[þ]... ...

(... ... Torgöt the... / ... spirit and Gods... ... )
