The Augustusburg Palace has been placed on the UNESCO World Heritage List. The palace is one of the key works of Balthasar Neuman, and contains one of the finest Rococo interiors in the world, the highlight being the main staircase. Entry to Augustusburg is only by guided tours that are on the hour. Also in the grounds is the magnificent hunting Lodge of Falkenlust, roughly 2km from Augustusburg. Tickets are available for each palace independently. Tickets to Falkenlust include an audio guide.
