The Saint-Pierre Abbey in Airvault was initially a collegiate church of regular canons of Saint Augustine, founded around 990 by Audéarde, wife of Viscount Herbert I of Thouars. As the canons were lax in following the rules of the Order of Saint Augustine, the Bishop of Poitiers decided to send a monk from the Augustinian abbey of Lesterps in Limousin to reform it. Pierre de Fonte Salubri (of Saine Fontaine) was appointed the first abbot of Airvault in 1096 and died on August 7, 1110. He undertook the construction of the abbey church. According to the Chronicle of Saint-Maixent, the church was consecrated in 1100 but subsequently underwent modifications and additions.
After the creation of the diocese of Maillezais in 1317, transferred to La Rochelle in 1648, the abbey became dependent on it.
During the Revolution a road was pierced through the abbey separating the convent buildings of the abbey. Several buildings are still visible as the room called the 'vat', the 'prison' (fortified gate), underground rooms, the fourteenth-century chapel and especially the abbey house which has hosted since 1975 the municipal museum.
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.
