Contributor mavic pro created this beautiful drone video from the Wachau Valley in northwestern Austria. The 32 km (roughly 20 mi.) valley, through which flows the Danube River, offers some of the most popular attractions in the state of Lower Austria. The video features footage of the ruined Dürnstein Castle, where Richard the Lionhearted was held captive following the Third Crusade. It also includes footage of the magnificent Göttweig Abbey, an 11th century Benedictine monastery.
