Introd castle stands on a promontory protected by the harsh gorges of the Savara and the Dora di Rhêmes (in fact the name Introd derives from the term Interaquas, or entre-eaux in French, which means “between the waters”) and probably dates back to the 12th century.
Like Graines castle, originally, it probably consisted of a square keep surrounded by a perimeter wall. Around 1260 Pierre Sarriod of Introd transformed the early castle which, following the modifications of the 15th century became five-sided and almost circular in shape, setting it apart from other castles in Val d’Aosta. These transformations mark the apogee of the Sarriod family, which included the Lords of Introd and La Tour (Saint-Pierre).
The castle was heavily damaged by two fires during the second half of the 19th century and was rebuilt at the start of the 1900s by Gonella, who engaged the architect Chevalley. Today it is owned by the Counts Caracciolo of Brienza and rented out for free to the Municipality of Introd. The ground floor and castle gardens are open to the public.
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.
