Library of Melk Abbey, in Melk, Austria
The library of the abbey of Melk, a famous Benedictine abbey overlooking the Danube founded in the 11th century, contains about 85,000 volumes, plus 1,200 manuscripts and incunabula (books printed before 1501). Its architecture is impressive, including the ceiling fresco by 18th-century Austrian Baroque painter Paul Troger depicting an allegory of the Faith. The wooden statues symbolize the four faculties: law, medicine, philosophy and theology.
