abuse involving Father Georg in the 1960s and Father Altman Kellner before and during the 1950s. In July 2013 an Austrian court found Mandorfer guilty in 24 documented cases of child abuse and sexual violence, and sentenced the now defrocked priest to twelve years in prison. In March 2015, a research team led by the German sociologist Heiner Keupp presented the results of a scientific study on the topic Sexual Abuse, psychological and physical Violence at the Kremsmünster boarding school, which identified a total of 16 violent and 8 sexual abusers within a period from 1945 until 2000. In 2013, it was revealed that the school had paid approximately €700,000 in compensation since the scandal erupted. Library The magnificent monastery library was built between 1680 and 1689, also by Carlo Antonio Carlone. It is one of the great libraries of Austria and contains about 160,000 volumes, besides 1,700 manuscripts and nearly 2,000 incunabula. The most valuable book is the "Codex Millenarius", a Gospel Book written around 800 in Mondsee Abbey. Facsimiles of this codex may be found in the libraries of a number of universities throughout the world. Treasures The most famous item of the treasury of the monastery is the Tassilo Chalice, donated to the monastery by its founder, Tassilo III. The copper and silver-gilt goblet (25.5 cm high, weighing 3 kg and holding 1.75 litres) was created some time between 768/769 and 788, possibly in Mondsee or Salzburg. The two Tassilo Candlesticks were originally thought to have been worked from the sceptre of Tassilo, but today are recognized as works of the mid 10th century. The Tassilo Chalice, the candlesticks and the Codex Millenarius are still used in religious services to this day, though only on special occasions.
