A site of Christian worship for more than 1,300 years, ancient Hexham Abbey forms one side of the town's main square. Inside, you can climb the 35 worn stone "night stairs," which once led from the main part of the abbey to the canon's dormitory, to overlook the whole ensemble. Most of the current building dates from the 12th and 13th centuries, and much of the stone, including that of the Anglo-Saxon crypt, was taken from the Roman fort at Corbridge. Note the portraits on the 16th-century wooden rood screen and the four panels from a 15th-century Dance of Death in the sanctuary. In September, the abbey hosts the renowned Festival of Music and the Arts, which hosts classical musicians from around the world.
