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:The Clementinum is a historic complex of buildings in Prague. Until recently the complex hosted the National, University and Technical libraries, the City Library also being located nearby on Mariánské Náměstí. The Technical library and the Municipal library have moved to the Prague National Technical Library at Technická 6 since 2009. It is currently in use as the National Library of the Czech Republic.
Its history dates from the existence of a chapel dedicated to Saint Clement in the 11th century. A Dominican monastery was founded in the medieval period, which was transformed in 1556 to a Jesuit college. In 1622 the Jesuits transferred the library of Charles University to the Klementinum, and the college was merged with the University in 1654. The Jesuits remained until 1773, when the Klementinum was established as an observatory, library, and university by the Empress Maria Theresa of Austria.
