Every year, The National Open Art Competition (NOA) gathers some of the finest and emerging artists and a host of industry luminaries from all across the art world for an exhibition of creativity, accolades and celebration.

Each year thousands visit the acclaimed show, joining in with the many activities and watching the artists in residence.

The artists entering NOA range from the highly acclaimed photographer Marcus Lyon, to the complete amateur artist working from home with sheer passion.

Entries cover all mediums from oil to moving image, watercolour to photography. NOA is open to everyone and judged anonymously.
