The old town was badly damaged when the Assad regime put down the uprising by the Muslim Brotherhood in 1982, but what is left of it still retains plenty of charm. The noria are large waterwheels that used to lift water from the Orontes River into a system of aqueducts that supplied the city and adjacent farmland. The wheels themselves have been restored, even if the (now thoroughly cleaned up) remaining sections of aqueduct are no longer in use. They are very impressive, and there are lots of pleasant gardens where you can sit close to them and have a coffee or snack. All in all, a fascinating and unexpectedly beautiful sight.
Just head for the town centre.
