Fécamp Abbey (French: Abbaye de la Trinité de Fécamp) is a Benedictine abbey in Fécamp, Seine-Maritime, Upper Normandy, France.
The abbey was the first producer of Bénédictine, a herbal liqueur, based on brandy.
It was founded in 658 by Waningus, a Merovingian count, for nuns. Another convent he founded in 660, near the site of the Precious Relic, was destroyed by the Vikings in 842. Around the Ducal palace, the foundations of two chapels have been found.
After more Viking raids, Richard I of Normandy rebuilt the church. It was Richard II who invited Guillaume de Volpiano (Guglielmo da Volpiano) in 1001 to rekindle the life of the abbey, under Benedictine rules. These two Norman rulers, who were originally buried outside, were later interred in 1162 by Henry II of England within the southern transept of the gothic abbey church. Guillaume de Volpiano is buried in one of the northern chapels.
The abbey at Fécamp was critical in the Norman conquest of England. Edward the Confessor granted the royal minster church in Steyning to the abbey, in gratitude to his Norman protectors during his exile. With its large, wealthy manor lands and thriving port, this grant was to take effect after the death of Aelfwine, Bishop of Winchester, who had charge of Steyning. The bishop died in 1047 and ecclesiastical jurisdiction then passed directly to Pope Clement II. In the same way, Fécamp Abbey itself answered to no Norman bishop, only to the Pope. The gift was later confirmed by William the Conqueror.
