Carl Gyllenhielm

He was made a baron (friherre) in 1615, appointed Field Marshal in 1616, Privy Councilor in 1617, Governor General of Ingria in 1617 and served as Lord High Admiral from 1620 until his death.

[1] He was an illegitimate son of Duke Carl, later King Charles IX of Sweden, and Karin Nilsdotter,[2] the daughter of a clergyman from Östergötland.

It was the tradition in Sweden in this period that noble children born out of wedlock were acknowledged by their fathers, as long as they were not the product of adultery.

[4] On 27 February 1617 the Treaty of Stolbovo ended the Ingrian War (1610–1617), fought between the Swedish Empire and Russia.

Karlberg was eventually taken over as an administrative headquarters for the Swedish military, but several of the central reception rooms are preserved as they were in Gyllenhielm's lifetime.
