Phnom Penh's Central Market was built in 1937 and at the time it was reputedly the largest market in Asia. Today it isn't even the largest market in Phnom Penh but it is a beautiful piece of architecture that is dominated by a central dome and four arms that radiate from the center in a cross shape. As a market it caters primarily to the tourists although there are areas where locals can shop for their staple foodstuffs or stop for a snack.
