In Norse times the city was just called Borg (from borg which means "castle"). The background for this was the fortification built by Olav Haraldsson (see History section). Later the genitive case of the name of the waterfall Sarpr (now Sarpsfossen) was added.
In Norse times Østfold county was called Borgarsýsla which means "the county (sýsla) of Borg" and the law district of southeast Norway was called Borgarþing meaning "the thing/court of Borg".
The coat-of-arms is from modern times. They were granted on 13 November 1991. It is based on a coat-of-arms from 1556. It shows a bear over a castle. The bear was introduced as early as sometime in the 13th century, by the earl of Sarpsborg (Comes de Saresburgh), Alv Erlingsson. He used the bear to symbolize his strength. The castle symbolizes the fortress (borg) that once gave the city its original name.
The city was founded as Borg by the Viking King Olav Haraldsson (Saint Olav) in 1016. It was burned to the ground by Swedish invaders in 1567 during the Northern Seven Years' War. Half the population was evacuated down the river to what is today known as Fredrikstad, about 15 kilometres (9 mi) downstream.
Much of the rebuilt town disappeared into the river Glomma during a 1702 mudslide. Again Borg was rebuilt, and it was recreated as a city in 1839, and separated from Tune as a municipality of its own.
In the 1960s, Sarpsborg was famous for its football (soccer) team, Sarpsborg FK, but is now more known for its ice hockey team, Sparta Warriors. In football, Sarpsborg 08 FF has taken over the local throne, currently playing on the highest national level. On 6 November 2009, they sent arch-rival FFK down from the "Tippeliga" in a play-off game in Fredrikstad stadion. Sarpsborg-08 has a women's football team that was promoted to the women's division-1 at the end of 2011, at the same time as the club's under-19 girls reached the Junior Cup Final. Sarpsborg BK plays in the highest bandy division.
