The Fassbau (Barrel Building) is best viewed from the Large Alton balcony. The Gothic windows were completely out of fashion when this functional building was erected at the end of the 16th century. Today, no one knows what prompted the commissioner of buildings Johann Kasimir, the uncle and guardian of the later Friedrich IV, to appoint them. A giant barrel was built into the building's cellar 1591. It held 130,000 litres (about 34,342 gallons) of wine collected from the Palatinate in payment of taxes.
