Inveraray Castle: An Ancient Archive Treasure Trove

Inveraray Castle is home to one of the most important private collections of historical archives in all of Britain—a collection of records, documents and diaries, dating back to the 13th century. The restoration of the private archival documents is a gradual, painstaking and expensive process. In fact, a single damaged page can cost up to a hundred pounds to repair. (02:37)
