The Sjöö Castle Palace with its park is considered one of the most beautiful in Sweden, with its perfect and harmonious proportions.

As the Marshal of the Realm of Sweden, Stenbock was a statesman, head of the court and chairman of the castle law.

The nearby Church of Holm—closely connected with the castle—was erected in 1678, under the watchful eyes of Andreas Hackzelius (1630–1681) who became the first Rector—head of congregation—of the Parish of Holm to utilize the new facilities.

The patronage of the Church of Holm then consisted of high-ranking statesmen and royal and other high noble friends and family members of Johan Gabriel Stenbock who owned Sjöö Castle.

Her son, Fredrik, was married to the famous Catherine Charlotte De la Gardie, who lived in the Castle between 1748 and 1763.
