A slate tablet honoring Manod quarry’s WWII role in sheltering National Gallery art is unveiled at the gallery.

The National Gallery has unveiled a slate tablet honoring Manod quarry in North Wales, where its art collection was hidden during World War II from 1941 to 1945. Made from local slate and inscribed in Welsh and English, the tablet commemorates the site’s role in protecting national artworks. Special brick shelters were built inside the quarry, and the entrance was expanded to accommodate large paintings. Created by artists Jeremy Deller and John Neilson and commissioned by Mostyn gallery, the tablet will be permanently displayed in the National Gallery’s Portico Vestibule as part of a broader celebration of British and Irish art and heritage.
