With an estimated height of at least 4 metres, the world's largest ox cart is a landmark at Wat Sam Roi Yot in Prachuap Khirikhan Province. Known in Thai as kwian, these two-wheeled carts are typically drawn by a pair of oxen (fig.), and were traditionally used to transport paddy to the market. Thailand's four regions each boast their own traditional cart designs, reflecting unique local craftsmanship and styles. This particular cart follows the design of western central Thailand, known as Kwian Ratchaburi.
