Göttweig Abbey was founded as a monastery of canons regular by Blessed Altmann, Bishop of Passau. The high altar of the church was dedicated in 1072, but the monastery itself not until 1083: the foundation charter, dated 9 September 1083, is still preserved in the abbey archives.
By 1094 the discipline of the community had become so lax that Bishop Ulrich of Passau, with the permission of Pope Urban II, introduced the Rule of St. Benedict. Prior Hartmann of St. Blaise's Abbey in the Black Forest was elected abbot. He brought with him from St. Blaise's a number of chosen monks, among whom were Blessed Wirnto and Blessed Berthold, later abbots of Formbach and Garsten respectively. Under Hartmann (1094–1114) Göttweig became a famous seat of learning and strict monastic observance. He founded a monastic school, organized a library, and at the foot of the hill built a nunnery where it is believed that Ava, the earliest German language poetess known by name (d. 1127), lived as an anchorite. The nunnery, which was afterwards transferred to the top of the hill, continued to exist until 1557.
During the 15th and 16th centuries however the abbey declined so rapidly that between 1556 and 1564 it had no abbot at all, and in 1564 not a single monk was left here. At this crisis an imperial deputation arrived at Göttweig, and elected Michael Herrlich, a monk of Melk Abbey, as abbot. The new abbot, who held his office until 1604, restored the monastery spiritually and financially, and rebuilt it after it had been almost entirely destroyed by fire in 1580.
Abbots distinguished during the Reformation were George Falb (1612–1631) and David Corner (1631–1648), who successfully opposed the spread of Protestantism in the district.
In 1718 the monastery burnt down and was rebuilt on a grander scale during the abbacy of Gottfried Bessel (1714-1749) to designs by Johann Lucas von Hildebrandt inspired by the Escorial, a scheme so lavish that Abbot Gottfried was nearly deposed because of it. The fresco decorating the imperial staircase is considered a masterpiece of Baroque architecture in Austria. Executed by Paul Troger in 1739, it represents the Holy Roman Emperor Charles VI as Apollo.
The abbey has a library of 130,000 books and manuscripts, and a particularly important collection of religious engravings, besides valuable collections of coins, antiquities, musical manuscripts and natural history, all of which survived the dangers of World War II and its immediate aftermath almost without loss.References:
German crusaders known as the Livonian Brothers of the Sword began construction of the Cēsis castle (Wenden) near the hill fort in 1209. When the castle was enlarged and fortified, it served as the residence for the Order's Master from 1237 till 1561, with periodic interruptions. Its ruins are some of the most majestic castle ruins in the Baltic states. Once the most important castle of the Livonian Order, it was the official residence for the masters of the order.
In 1577, during the Livonian War, the garrison destroyed the castle to prevent it from falling into the control of Ivan the Terrible, who was decisively defeated in the Battle of Wenden (1578).
In 1598 it was incorporated into the Polish-Lithuanian Commonwealth and Wenden Voivodship was created here. In 1620 Wenden was conquered by Sweden. It was rebuilt afterwards, but was destroyed again in 1703 during the Great Northern War by the Russian army and left in a ruined state. Already from the end of the 16th century, the premises of the Order's castle were adjusted to the requirements of the Cēsis Castle estate. When in 1777 the Cēsis Castle estate was obtained by Count Carl Sievers, he had his new residence house built on the site of the eastern block of the castle, joining its end wall with the fortification tower.
Since 1949, the Cēsis History Museum has been located in this New Castle of the Cēsis Castle estate. The front yard of the New Castle is enclosed by a granary and a stable-coach house, which now houses the Exhibition Hall of the Museum. Beside the granary there is the oldest brewery in Latvia, Cēsu alus darītava, which was built in 1878 during the later Count Sievers' time, but its origins date back to the period of the Livonian Order. Further on, the Cēsis Castle park is situated, which was laid out in 1812. The park has the romantic characteristic of that time, with its winding footpaths, exotic plants, and the waters of the pond reflecting the castle's ruins. Nowadays also one of the towers is open for tourists.
