Hautvillers Abbey is a former Benedictine monastery in the Hautvillers commune of the Marne department in north-eastern France. The abbey remained active between 665 and the French Revolution of 1789. It housed the relics of Saint Helena, Empress and mother of Constantine, between 841 and 1819. One of its monks, Dom Pérignon, contributed to the development of sparkling wine in the Champagne region.
The abbey was founded in 650 by Saint Nivard, Bishop of Reims. According to legend, a dove indicated where to build an abbey that would follow the order of Saint Benedict and Saint Columbanus. The abbey flourished under the Carolingian Dynasty and drew great renown thanks to its manuscripts, such as the Ebbo Gospels and perhaps the Utrecht Psalter.
Saint Rieul joined the abbey in 662, before succeeding Saint Nivard as Archbishop of Reims in 669. In 841 a priest from Reims stole the relic of the body of Saint Helena from Rome and the reliquary was transferred to the abbey. The relics attracted pilgrims and the revenues allowed the abbey to purchase lands and vineyards in the vicinity (40 hectares).
The remaining relics of St. Helena stayed in the monastery until the French Revolution broke out. The monastery was destroyed but the cellarer was able to hide the relics until they could be safely transported to Paris for public veneration again. They were then entrusted to the Knights of the Holy Sepulchre and installed in their church, Saint-Leu-Saint-Gilles de Paris,in 1819.
References:Visby Cathedral (also known as St. Mary’s Church) is the only survived medieval church in Visby. It was originally built for German merchants and inaugurated in 1225. Around the year 1350 the church was enlarged and converted into a basilica. The two-storey magazine was also added then above the nave as a warehouse for merchants.
Following the Reformation, the church was transformed into a parish church for the town of Visby. All other churches were abandoned. Shortly after the Reformation, in 1572, Gotland was made into its own Diocese, and the church designated its cathedral.
There is not much left of the original interior. The font is made of local red marble in the 13th century. The pulpit was made in Lübeck in 1684. There are 400 graves under the church floor.
