Kresen Kernow - Riverstone Ultra

Kresen Kernow is the state-of-the-art facility that houses the world’s largest collection of Cornish documents, books, maps, and photographs, dating from 1150 to the present day.

The site provides a suite of public search rooms, conservation and preservation workshops, exhibition spaces, education rooms, and associated staff and volunteer facilities, while a new two storey extension provides archive storage in closely controlled environmental conditions, designed to BS5454 conservation standard.

For the roof, the building’s designers wanted the closest match possible to Delabole – the indigenous Cornish slate that’s now extremely difficult to source.
