Moosburg

St. Kastulus, Moosburg, existed as a Benedictine monastery from the 8th century until 1021. In 1021, it was changed into a community for canons (a collegiate monastery), while the Benedictines were moved to nearby Weihenstephan (Freising). The monastery's patron saint Kastulus is a Roman martyr and catacomb saint. After the collegiate monastery was relocated to Landshut (1598), Kastulus's relics were translated to the city likewise. Landshut's parish church, St. Martin, was raised to a collegiate church. Following the community's dissolution in the wake of the secularisation of 1803, a major part of the library, including medieval manuscripts, became the property of the Ludwig Maximilian University, which had moved to Landshut in 1800. The university relocated again in 1826, and since then these books have been held by the University Library in Munich. Further parts of the former Moosburg Library ended up in the Royal Court Library (Königliche Hofbibliothek) in Munich (today's Bayerische Staatsbibliothek)
