The former Polling monastery library was once the second largest library in Bavaria, after the Munich court library.[1] It belonged to the Polling Abbey which was dissolved during secularisation in Bavaria. Around 1631, its number of books was still relatively small and mainly from the area of theology.[2] The greatest growth rates of books were during the era of provost Franz Töpsl during the Age of Enlightenment. Before provost Töpsel, 20,000 volumes were shelved in the library.[3] A large proportion of the books of 80,000 volumes were given to today's Bavarian State Library and the Ingolstadt University Library. In these books were included 653 manuscripts and 1394 incunabula.[3]
The impressive library hall is now used for concerts and events. The library was built from 1776 to 1778.[2] The master builder of the library was Matthias Bader, the ceiling fresco was painted by Johann Baader, and the stucco was by Thassilo Zopf.[4] After secularisation, around 1814, the Streicher family bought the building, who used the large hall as storage.[5] During the Second World War about 800 paintings of the Bavarian State Painting Collections were stored here, some of them very valuable.[6] In November 1971, members of the Rotary Club of Weilheim founded a club to renovate the library hall and make it available to the public.[7] Since 1975, the hall has been regularly used for classical concerts. Several hundred concerts have already been held here.
