Klosterneuburg Monastery was founded in 1114 by Saint Leopold III of Babenberg, the patron saint of Austria, and his second wife Agnes of Germany. In 1136, the abbey church was consecrated after 22 years of construction. The form of that original basilica has survived for nine centuries, despite many subsequent modifications and reconstructions.
The abbey church, dedicated the Nativity of Mary, was later remodeled in the Baroque style in the 17th century. The impressive monastery complex was mostly constructed between 1730 and 1834. Its foundations, including a castle tower and a Gothic chapel, date back to the 12th century. Other older buildings still extant within the complex include the chapel of 1318 with Saint Leopold's tomb. From 1634 on, the Habsburg rulers had the facilities rebuilt in the Baroque style, continued by the architects Jakob Prandtauer and Donato Felice d'Allio. The plans to embellish the monastery on the scale of an Austrian Escorial were later resumed by the Neoclassical architect Joseph Kornhäusel, though only small parts were actually carried out. In 1879, the abbey church and monastery were restored according to plans by Friedrich von Schmidt, and the neo-Gothic twin steeples were erected.
Klosterneuburg Monastery contains the Verduner Altar, made in 1181 by Nicholas of Verdun. Its three parts comprise 45 gilded copper plates modeled on Byzantine paragons, similar to the Shrine of the Three Kings at Cologne Cathedral. The monastery also contains a museum with a collection of Gothic and Baroque sculpture and a gallery of paintings, including fifteen panel paintings by Rueland Frueauf from 1505, four Passion paintings from the backside of the Verduner Altar from 1331, and the Babenberg genealogical tree.
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.
