Edzell Castle is a 16th-century ruined fortress near Brechin in Angus, Scotland, renowned for its remarkable early-17th-century walled garden created in 1604. The castle originated around 1520 under David Lindsay, 9th Earl of Crawford, and hosted notable royal guests including Mary Queen of Scots and James VI. The distinctive ornamental garden features box-trimmed parterres representing the Fleur de Lys, Scottish Thistle, and English Rose, along with fine carved stone panels depicting the Seven Cardinal Virtues, Seven Liberal Arts, and Seven Planetary Deities. The site operates seasonally and remains one of Scotland's finest examples of Renaissance garden design.
