A monastery was founded in Lambach in about 1040 by Count Arnold II of Lambach-Wels. His son, Bishop Adalbero of Würzburg, changed the monastery into a Benedictine abbey in 1056, which it has been since. During the 17th and 18th centuries a great deal of work in the Baroque style was carried out, much of it by the Carlone family. Lambach escaped the dissolution of the monasteries of Emperor Joseph II in the 1780s.
Adolf Hitler attended the monastery as a boy and saw swastikas on the woodwork. He later used it as a symbol for the Nazi Party, and placed it on a white circle and red background for use as a flag.
The abbey has preserved much of cultural interest. It contains the oldest extant Romanesque frescoes in Southern Germany and Austria, and the former abbey tavern, now a pharmacy, with a beautiful Baroque façade. The abbey's Baroque theatre has also been restored to working order and the summer refectory from the early 18th century by Carlo Antonio Carlone has been converted into a concert hall. The ambulatory by Diego Carlone from the same period is of great magnificence. An unexpected feature is the set of Baroque dwarves in the monastery garden.
The abbey church was also refurbished in the Baroque style, with an organ by Christoph Egedacher and contains the tomb of Saint Adelbero. The abbey also possesses the medieval St. Adelbero's Chalice, although it is rarely on view to the public, besides a large collection of sacred art. The library was constructed about 1691 and contains approximately 50,000 volumes as well as archive material.

Its history dates from the existence of a chapel dedicated to Saint Clement in the 11th century. A Dominican monastery was founded in the medieval period, which was transformed in 1556 to a Jesuit college. In 1622 the Jesuits transferred the library of Charles University to the Klementinum, and the college was merged with the University in 1654. The Jesuits remained until 1773, when the Klementinum was established as an observatory, library, and university by the Empress Maria Theresa of Austria.
