Kyffin Williams generously donated over 400 original works of art to Oriel Môn throughout his life, ranging from sketches to drawings to major oil paintings.

This gallery opened its doors to the public in 2008 and since then it has exhibited hundreds of artworks by the artist itself, as well as work by other internationally important artists.

There are two exhibitions held here every year, showing works from Oriel Môn's vast collection as well as works loaned from international institutions and private collections.

Sir Kyffin Williams Drawing Prize

The biennial Sir Kyffin Williams Drawing Prize is also held here, a national drawing competition established by the Sir Kyffin Williams Trust as a tribute to the support that Kyffin gave to artists and the value that he placed on drawing skills.
