A portrait of Ebenezer Howard and the original Letchworth masterplan are currently on loan at the National Portrait Gallery.

The exhibition, Anarchy and Beauty: William Morris and His Legacy, explores the influence of his ideas on art, craft and society – featuring Spencer Pryse’s portrait of Howard in the garden cities section of the Wolfson Gallery.

Barry Parker and Raymond Unwin’s masterplan is a central exhibit, emphasising their innovative thinking about integrating architectural planning and natural beauty.

Garden City Collection curator Vicky Axell said: “This is a fantastic opportunity to highlight the success of Howard’s first garden city to a wider audience.

“William Morris influenced so many during his lifetime, including the work of Ebenezer Howard and Letchworth architects Parker and Unwin.”

The exhibition runs until January 11.
