Melk is an Austrian town on the River Danube, west of Vienna. It's known for the 11th-century Melk Abbey, a vast monastery built high above the town. Gold statuary adorns its domed Abbey Church, and the huge library houses medieval manuscripts. The Marmorsaal is a baroque hall with a ceiling fresco and red marble walls. South of Melk, gardens surround Renaissance Schallaburg Castle, which hosts cultural exhibitions.
