Füssen's landmark, the Hohes Schloss (high castle), sits on a high rock and overlooks the village. Hohes Schloss is one of Bavaria's largest and best-preserved Gothic castle complexes, and is the former summer residence and fortress of the prince bishops of Augsburg.
The first castle on the hill dates back to the age of Roman Empire. The current castle was built in the 13-15th century. It was already integrated to city fortifications in 1363 and largely extended and renovated by bishop Friedrich II in the late 1400s and again around 1680 by Prince Bishop Johann Christoph von Freyberg.
The north wing of the palace contains the Staatsgalerie (State Gallery), with regional paintings and sculpture from the 15th and 16th centuries. The Städtische Gemäldegalerie (City Paintings Gallery) below is a showcase of 19th-century artists.
The inner courtyard is a masterpiece of illusionary architecture dating back to 1499.References:
Built around AD 90 to entertain the legionaries stationed at the fort of Caerleon (Isca), the impressive amphitheatre was the Roman equivalent of today’s multiplex cinema. Wooden benches provided seating for up to 6,000 spectators, who would gather to watch bloodthirsty displays featuring gladiatorial combat and exotic wild animals.
Long after the Romans left, the amphitheatre took on a new life in Arthurian legend. Geoffrey of Monmouth, the somewhat imaginative 12th-century scholar, wrote in his History of the Kings of Britain that Arthur was crowned in Caerleon and that the ruined amphitheatre was actually the remains of King Arthur’s Round Table.
Today it is the most complete Roman amphitheatre in Britain.
