"For many centuries, the Hohenzollerns were one of Germany ’s most powerful families, their influence only diminishing with the end of the monarchy after World War I. During their dominance, they lived in this majestic neo-Gothic castle, visible from miles away thanks to its prime location on a conical hill. Inside, a series of opulent rooms remain resplendent with period furnishings and valuable oil paintings. The Treasury—which hosts personal items of Frederick the Great and Queen Louise, the Prussian Royal Crown, and a great deal of expensive porcelain and silverware—and the royal chambers can only be seen via a guided tour, but the grounds are free to explore. Also open to the public is the café-restaurant Burg Hohenzollern, with decent regional food and an outdoor beer garden in summer."
