The Royal Castle in Brave was inspired by Eilean Donan Castle in Scotland. Though the current castle standing on Eilean Donan (which means “island of Donnan” in Gaelic) is a reconstruction completed in 1932, the island has an ancient history. It is said to have been the site of a monastery in the 6th or 7th century, and it later became home to a castle that protected the Mackenzie clan.
