The Castle of Châteauneuf-du-Pape was probably originally a Roman castrum destroyed during the great invasions. A 913 charter referred to the castellum de Leri. The first mention of a Castro Novo (new fortified village), which led to the name Châteauneuf, did not appear until 1048. In 1077 the keep was built there. Throughout the Middle Ages, the old château was a watchtower and a toll gate on the Rhône that passed to various families allied to the house of Albaron. Only a tower remained in 1146, and by 1283 it was already being referred to as 'the old tower'.
Jacques d'Euze, previously the bishop of Avignon, was elected pope in 1316 and took the name John XXII. Châteauneuf fell directly under his authority. Then in 1317 he decided to build a new château above the village. It was finished in 1333. Due to its size and location its function was essentially defensive At the same time, in 1318, he circled it with ramparts.
After the Popes returned to Rome in the early 15th century, the castle was abandoned, for the bishops did not have the means to maintain the castle. During the years which followed, the castle underwent the vicissitudes of time, including times of strife such as the Wars of Religion in the 16th century. In 1892 it was ranked as a historical monument, and was again damaged during the World War II.
Today, all that remains is a sungeon, the southern wall, and the lower pontifical cellar. The castle is the emblem of the town of Châteauneuf-du-Pape and is often used for local receptions and wine events, such as the Councils of the Echansonnerie des Papes, the Bacchic Brotherhood of Châteauneuf-du-Pape Wines.
Saint-Georges de Boscherville Abbey is a former Benedictine abbey. It was founded in about 1113 by Guillaume de Tancarville on the site of an earlier establishment of secular canons and settled by monks from the Abbey of Saint-Evroul. The abbey church made of Caumont stone was erected from 1113 to 1140. The Norman builders aimed to have very well-lit naves and they did this by means of tall, large windows, initially made possible by a wooden ceiling, which prevented uplift, although this was replaced by a Gothic vault in the 13th century. The chapter room was built after the abbey church and dates from the last quarter of the 12th century.
The arrival of the Maurist monks in 1659, after the disasters of the Wars of Religion, helped to get the abbey back on a firmer spiritual, architectural and economic footing. They erected a large monastic building one wing of which fitted tightly around the chapter house (which was otherwise left as it was).
