Hallvard Vebjørnsson
Norwegian Christian saint (c. 1020–1043)
Hallvard Vebjørnsson (Hallvard Den Hellige) (c. 1020–1043), commonly referred to as Saint Hallvard (Sankt Hallvard), is the patron saint of Oslo. He is considered a martyr because of his defence of an innocent thrall woman. His religious feast day is 15 May.
The connection of St. Hallvard to the city of Oslo was evidenced by the fact that his image was recorded in the city's seal since the Middle Ages. The municipality's highest honor, the St. Hallvard Medal (St. Hallvard-medaljen), was named after him in 1950.[2]
