The Neumoustier Abbey was built sometime after 1109 in the city of Huy, Belgium. Today, a mansion with gardens have been built on the site. It was an Augustinian abbey dedicated to the Holy Sepulchre and Saint John the Baptist.
Legend has it that Conon, Count of Montaigu, his son Lambert, and Peter the Hermit were returning by ship from the First Crusade when they encountered a fierce storm. They vowed to build a church of God if they were saved, and the storm immediately abated. The Neumoustier Abbey is the result of this apparently divine intervention. Peter lived at the abbey until his death in 1115 where he was entombed.
The abbey also served as a popular pilgrimage destination itself. According to local legend, pilgrims who could not fulfill their vows to travel to Jerusalem earned the same spiritual benefits by traveling the shorter destination to the abbey itself.
