Scotland's largest indoor market—named for the barrows, or pushcarts, formerly used by the stallholders—is a must-see for anyone addicted to searching through piles of junk for bargains. The century-old institution, open weekends, consists of nine markets. The atmosphere is always good-humored, and you can find just about anything here, in any condition, from dusty model railroads to antique jewelry. Haggling is compulsory. You can reach the Barras by walking along Argyle Street from the St. Enoch subway station.
