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 Basilica of Santa Maria in Trastevere is one of the oldest churches of Rome. The basic floor plan and wall structure of the church date back to the 340s, and much of the structure to 1140-43. The first sanctuary was built in 221 and 227 by Pope Callixtus I and later completed by Pope Julius I.
The inscription on the episcopal throne states that this is the first church in Rome dedicated to Mary, mother of Jesus, although some claim that privilege belongs to the Basilica di Santa Maria Maggiore. A Christian house-church was founded here about 220 by Pope Saint Callixtus I (217-222) on the site of the Taberna meritoria, a refuge for retired soldiers. The area was made available for Christian use by Emperor Alexander Severus when he settled a dispute between the Christians and tavern-keepers.
The church underwent two restorations in the fifth and eighth centuries and in 1140-43 it was re-erected on its old foundations under Pope Innocent II.
