A massive preservation effort is currently underway at the Pannonhalma Archabbey, a 1,000-year-old Benedictine monastery located in northwestern Hungary. Recognized as a UNESCO World Heritage site, the abbey is one of the country’s oldest religious and cultural institutions. During a routine cleaning, library workers discovered that thousands of books were infested with drugstore beetles, which typically feed on dried food but are also attracted to the adhesives in handbound books. About 100,000 books, equivalent to one-fourth of the monastery’s entire 400,000-volume archive, have been impacted by the infestation. The monastery, established in 996, houses Hungary’s earliest written records and rare manuscripts, including 19 codices and a 13th-century Bible. Experts fear that the damage could lead to the irrevocable loss of cultural and religious heritage, as some of the works are irreplaceable.

Restoration teams have implemented an intensive disinfection process to combat the infestation. The books are being packed into hermetically sealed plastic containers filled with nitrogen to eliminate oxygen, creating an environment where the beetles cannot survive. This procedure will continue for six weeks. Afterward, each book will undergo meticulous inspection and cleaning, with damaged volumes set aside for specialized restoration. The chief restorer suggested that rising temperatures caused by climate change may have exacerbated the problem by allowing the beetles to reproduce more frequently. This unprecedented situation has compelled the abbey to take urgent measures to safeguard its venerable collection, aligning with a monastic obligation to treat cultural property with the utmost reverence.
