The foundation of the Benedictine abbey Caunes-Minervois was the work of Aniane, Saint Benoît d'Aniane's friend, at the end of the 8th century. Originally under the direct protection of the King of France, the monastery later passed into the hands of the Count of Barcelona, before ending up as a possession of the Trencavel family who decided to renounce their rights in 1195.
During the Crusade against the Albigensians, several times, the Abbot of Caunes welcomed the Pope's representatives who came to preach the Catholic orthodoxy. In 1227, Pierre Isarn, the Cathar bishop of the Carcasses area was burned at the stake at Caunes.
The 13th and 14th centuries were marked by power struggles between secular and religious authorities, and by prosperity for the monastery whose members increased from about fifteen to about thirty.
The establishment, in 1467, of a commendam whereby a manager took over the running of the abbey, signalled the beginning of the decline of monastic values at Caunes. It was only at the beginning of the 17th century that a series of reforms was instigated by the Abbot Jean d'Alibert. In particular, he restored the buildings and re-built the abbey's residence. Then, the congregation of Saint-Maur took possession of the abbey in 1663 and rebuilt the moastic buildings. The abbey became state property in 1791, with the exception of the church which became property of the municipality.
References:The Chapel of St. Martin is the only completely preserved Romanesque building in Vyšehrad and one of the oldest in Prague. In was built around 1100 in the eastern part of the fortified outer ward. Between 1100 and 1300, the Rotrunda was surrounded by a cemetery. The building survived the Hussite Wars and was used as the municipal prison of the Town of the Vyšehrad Hill.
During the Thirty Years’ War, it was used as gunpowder storage, from 1700 to 1750, it was renovated and reconsecrated. In 1784, the chapel was closed passed to the military management which kept using it as a warehouseand a cannon-amunition manufacturing facility. In 1841, it was meant to be demolished to give way to the construction of a new road through Vyšehrad. Eventually, only the original western entrance was walled up and replaced with a new one in the sountren side. The dilapidating Rotunda subsequently served as a shelter for the poor.
