Tichy and Z. Moravec at Klet. Hluboká nad Vltavou is the most popular chateau in South Bohemia. The original thirteenth-century Gothic castle was rebuilt in Tudor style by the Schwarzenberg family during the nineteenth century. This typical English style gives the chateau almost an elfin appearance, which is accentuated by a vast park.
