Wessobrunn Abbey was founded in about 753 and dedicated to Saint Peter. According a legend Duke Tassilo III of Bavaria was hunting nearby and had a vision of three springs, which his servant Wezzo duly discovered the next day (the name means Wesso or Wezzo's spring(s)). The three springs are still to be seen, but there is otherwise no evidence of the truth of the story, and it is likely that the founders were a local noble family called Rott.
The first monks came from Niederaltaich Abbey under Ilsung, the first abbot. The church was dedicated to Saints Peter and Paul. During the rule of the second abbot, Adelmar (799–831), the monastery was transferred from the Diocese of Brixen to that of Augsburg. In 788 Wessobrunn became a Carolingian Empire Imperial abbey (independent of other terrorial lordships and answerable only to the monarchy) In about 900 it became a property of the Bishop of Augsburg.
In 955 the abbey was destroyed by the Hungarians, on which occasion Abbot Thiente and six of his monks suffered martyrdom, while the remaining three fled to Andechs with the sacred relics. The site was then occupied by canons until 1065, when the provost Adalbero restored the Rule of St. Benedict and governed as abbot until his death in 1110. In the first year of his abbacy the monastic church was rebuilt and was dedicated by Bishop Embrico of Augsburg.
Adalbero was succeeded by Sigihard (1110–28), during whose reign a separate church was built for the people of the surrounding area, dedicated to Saint John the Baptist in 1128. Under Blessed Waltho (1129–57) Wessobrunn enjoyed its first era of great spiritual and temporal prosperity. He was responsible for a number of unusually fine buildings. Also under Waltho the nunnery attached to the abbey between about 1100 and 1220 was of note as the home of Blessed Wulfhildis and Diemoth. In or around 1220 the church burnt down, and the monastery complex was extensively rebuilt at this time.
In 1401 the abbots of Wessobrunn were granted the right of pontifical insignia. A new era of great prosperity began with the accession of Ulrich Stocklin (1438–43), who had previously been a monk at Tegernsee Abbey and acquired considerable fame as a writer of sacred hymns.Abbot Heinrich Zach (1498–1508) installed a printing press at the monastery.
In 1680 Abbot Leonard Weiss (1671–96) began the rebuilding of the church and monastery on a far more lavish scale in the Baroque style, using the abbey's own stuccoists. He was also instrumental in the formation of the Bavarian Congregation in 1684 and joined his abbey to it.
The abbey was dissolved in 1803 in the course of the secularisation of Bavaria, when it came into the possession of a certain De Montot. From 1810 the site was extensively exploited for building materials to rebuild the nearby town of Weilheim, which had been damaged in a fire. What remained in 1861 was saved by Professor Johann Nepomuk Sepp, who bought the site and preserved it. In 1900 it was acquired by Baron von Cramer-Klett.References:
From its origin as a small stronghold built by the ancient Illyrian tribe Dalmatae, becoming a royal castle that was the seat of many Croatian kings, to its final development as a large fortress during the Ottoman wars in Europe, Klis Fortress has guarded the frontier, being lost and re-conquered several times. Due to its location on a pass that separates the mountains Mosor and Kozjak, the fortress served as a major source of defense in Dalmatia, especially against the Ottoman advance, and has been a key crossroad between the Mediterranean belt and the Balkan rear.
Since Duke Mislav of the Duchy of Croatia made Klis Fortress the seat of his throne in the middle of the 9th century, the fortress served as the seat of many Croatia"s rulers. The reign of his successor, Duke Trpimir I, the founder of the Croatian royal House of Trpimirović, is significant for spreading Christianity in the Duchy of Croatia. He largely expanded the Klis Fortress, and in Rižinice, in the valley under the fortress, he built a church and the first Benedictine monastery in Croatia. During the reign of the first Croatian king, Tomislav, Klis and Biograd na Moru were his chief residences.
In March 1242 at Klis Fortress, Tatars who were a constituent segment of the Mongol army under the leadership of Kadan suffered a major defeat while in pursuit of the Hungarian army led by King Béla IV. After their defeat by Croatian forces, the Mongols retreated, and Béla IV rewarded many Croatian towns and nobles with 'substantial riches'. During the Late Middle Ages, the fortress was governed by Croatian nobility, amongst whom Paul I Šubić of Bribir was the most significant. During his reign, the House of Šubić controlled most of modern-day Croatia and Bosnia. Excluding the brief possession by the forces of Bosnian King, Tvrtko I, the fortress remained in Hungaro-Croatian hands for the next several hundred years, until the 16th century.
Klis Fortress is probably best known for its defense against the Ottoman invasion of Europe in the early 16th century. Croatian captain Petar Kružić led the defense of the fortress against a Turkish invasion and siege that lasted for more than two and a half decades. During this defense, as Kružić and his soldiers fought without allies against the Turks, the military faction of Uskoks was formed, which later became famous as an elite Croatian militant sect. Ultimately, the defenders were defeated and the fortress was occupied by the Ottomans in 1537. After more than a century under Ottoman rule, in 1669, Klis Fortress was besieged and seized by the Republic of Venice, thus moving the border between Christian and Muslim Europe further east and helping to contribute to the decline of the Ottoman Empire. The Venetians restored and enlarged the fortress, but it was taken by the Austrians after Napoleon extinguished the republic itself in 1797. Today, Klis Fortress contains a museum where visitors to this historic military structure can see an array of arms, armor, and traditional uniforms.
