Francis Younghusband visited Turpan in 1887 on his overland journey from Beijing to India. He said it consisted of two walled towns, a Chinese one with a population of no more than 5,000 and, about a mile (1.6 km) to the west, a Turk town of "probably" 12,000 to 15,000 inhabitants. The town (presumably the "Turk town") had four gateways, one for each of the cardinal directions, of solid brickwork and massive wooden doors plated with iron and covered by a semicircular bastion. The well-kept walls were of mud and about 35 ft (10.7 m) tall and 20 to 30 feet (6 to 9 m) thick, with loopholes at the top. There was a level space about 15 yards (14 m) wide outside the main walls surrounded by a musketry wall about 8 ft (2.4 m) high, with a ditch around it some 12 ft (3.7 m) deep and 20 ft (6 m) wide). There were drumtowers over the gateways, small square towers at the corners and two small square bastions between the corners and the gateways, "two to each front." Wheat, cotton, poppies, melons and grapes were grown in the surrounding fields.
