Upplands runinskrifter 53, Stockholm

Upplands runinskrifter 53 is a Viking-Age runestone built into the corner of a house where Kåkbrinken meets Prästgatan in Gamla stan. Its carved face is turned toward Prästgatan, so the winding animal design is visible in the wall beside the old cannon barrel protecting the corner. The stone measures 0.95 metres by 0.55 metres and is damaged, though much of its inscription survives.

Torsten and Frögunn raised it in memory of their son, whose name has been lost. A cross-shaped mark was added to the carving, reinforcing its Christian meaning. The stone belongs to the later eleventh-century tradition of Uppland carving, dated to about 1070-1100. It was recorded by Johannes Bureus in the seventeenth century, removed for cleaning in 1937, and then returned to the same wall in a more visible, better-protected position.
