One of the oldest castles in Switzerland, Castle Spiez was built in 933 when much of the western area of modern-day Switzerland was ruled by Italy. Construction on the original keep continued for the next six centuries, offering you a unique opportunity to view a variety of architectural styles. The ancient Castle Church, for example, exemplifies the Early Romanesque style. The court rooms were built in the height of the Renaissance Era. The southern addition was finished in 18th century in the elaborate Baroque style.
