Yester Castle is a ruined fortress located near Gifford in East Lothian, Scotland, dating from before 1267 when it was built by Sir Hugo de Giffard. The castle is renowned for its legendary Goblin Ha', a substantial subterranean cavern whose construction is attributed in local lore to magical artifice. The site features the remnants of stone towers and a fabulous arch slowly being reclaimed by nature, and is a scheduled ancient monument. The castle's history is steeped in tales of its founder, known as 'The Wizard of Yester', whose supposed pact with the Devil allegedly raised a magical army of hobgoblins to construct the fortress.
