For example, many workers, over a decade, and massive monetary donations were spent to restore the Mappa Mundi and Chained Library museum located in Hereford, England.[1] Built over 900 years ago, the library fell into disrepair and faced destruction.[4] The oldest chained book found in the library is the Hereford Gospels.[8] Written in the eighth century, it is one of 229 chained books located in this great library.[8] The Hereford library is the largest surviving chained library with its chains and books intact.[8] The library is now open to the public as a tourist attraction and museum.[4]
