Strängnäs became a city of importance in the Södermanland province, as the location of the governing thing and also of an annual market.

The urban and economic development of Strängnäs seems to have slowed after the Reformation, only flourishing temporarily with the arrival of energetic bishops.

A significant fire in 1871 led to large-scale reconstruction of the city, from which time its current appearance stems.

The city was accidentally bombed by the Soviet Union during World War II, causing minor damage.

The stone is a piece of jotnian sandstone inscribed with runes written in Proto-Norse, in Elder Futhark alphabet.
