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.

Inveraray Castle is a country house near Inveraray in the county of Argyll, in western Scotland, on the shore of Loch Fyne, Scotland’s longest sea loch. It is one of the earliest examples of Gothic Revival architecture. It has been the seat of the Dukes of Argyll, chiefs of Clan Campbell, since the 18th century.
