Tholey Abbey is a Benedictine monastery dedicated to Saint Maurice. As early as the 5th and 6th centuries a group of clerics had established themselves here in the Roman ruins. On the instructions of Magnerich, bishop of Trier from 566 to 600, these hermits formed themselves into monastic communities. One of the earliest of such communities, at the foot of the Schaumberg, is said to have had Saint Wendelin as its head, who is thus counted by tradition as the first abbot of Tholey.
The Benedictine history of Tholey is thought to have begun in about 750. At the end of the 15th century the abbey joined the Bursfelde Congregation.
In 1794 during the French Revolution the abbey was plundered and burnt down, and dissolved the same year. In 1798 the remaining buildings were auctioned off. In 1806 they became the property of the municipality, as the parish church and priest's house.
The present abbey was established by the Benedictines in 1949 and settled in 1950 by monks from St. Matthias' Abbey, Trier. The monks work in pastoral care and run the guesthouse and book shop. As of 2020, twelve monks from five nations reside in the monastery.
in 2008, with philanthropic support from Edmund and Ursula Meiser, the chapter house was renovated, and baroque-style pavilion was erected on the grounds of the abbey.
In 2020, the abbey installed stained glass windows created by German artists Gerhard Richter and Mahbuba Maqsoodi. Richter's three windows — with deep reds and blues prevailing on the two outer displays and the central one dominated by radiant gold — are more than 30 feet tall and made to a symmetrical design. Maqsoodi's 34 windows for the church feature figurative images portraying saints and scenes from the Bible.
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.
