The royal group visited Dumbarton Castle on 17 August 1847, sailing up the Clyde from Greenock. Victoria noted the castle’s royal associations with William Wallace and Mary, Queen of Scots. Hildebrandt, court painter to the King of Prussia, visited Britain in early 1848 to make watercolours of Windsor Castle for his patron. Queen Victoria saw Hildebrandt at work and commissioned her own series of views related to her sightseeing the previous summer.
