THE SIR DENIS MAHON FOUNDATION was created by Sir Denis in his lifetime.
It aims to continue his philanthropic work, his art historical research and his passionate promotion of young scholars.
It promotes his art collection and lifelong work and studies to the general public, organises exhibitions, supports museums, and also endows three annual prizes for young scholars and artists, the Sir Denis Mahon Essay Prize, the Mahon Award, a drawing prize at The Royal Drawing School, and the Sir Denis Mahon Sculptural Project Grant in collaboration with City & Guilds of London Art School.

squinch
by Magnus Rena
We are delighted to announce the recent launch of Squinch, a literary/architecture magazine, founded by Magnus Rena, who was the recipient of the Sir Denis Mahon 2018 Essay Prize.
Squinch is a publication about architecture, art, and the way spaces shape feeling. It is independent, intelligent, and a little eccentric. Huge Congratulations Magnus!
The first issue features Charlie Porter, Ella Frears, Phineas Harper, Jonathan Glancey, Eyal Weizman and Forensic Architecture.
There was a presentation recently at the National Gallery in London for the George Beaumont Patrons, at the Julia and Hans Raising Gallery, Room 32, exploring the remarkable legacy of Sir Denis Mahon (1910-2011).
Francesca Whitlum-Cooper, Curator of Later Italian, Spanish and French Paintings, guided the Patrons through the gallery and shared fascinating insights into Mahon’s extraordinary contribution to the National Gallery. His generosity, scholarship and passion for Italian Baroque painting have left an indelible mark on the National Gallery’s Collection.
Suzanne Marriott represented the Sir Denis Mahon Foundation and met with Meredith Loper, recipient of the Sir Denis Mahon Essay Prize 2022, now Legacy and Appeals Manager at the National Gallery, London.
The wonderful 1996 photograph of Sir Denis Mahon shows him in Room 32, sitting in front of Guido Reni’s The Adoration of the Shepherds (dated approx. 1640).
The picture shown behind Suzanne and Meredith shows Guido Reni’s Rape of Europe, one of the many masterpieces gifted by Sir Denis to the National Gallery, London.

LEONARDO PASSERI
AB ORIGINE – The Beginning is the End
Solo Exhibition | Perugia, Italy | 20 November 2026
Leonardo Passeri, Permanent Artist-in-Residence at The Sir Denis Mahon Foundation, presents AB ORIGINE, a solo exhibition exploring the eternal cycle of creation, transformation and dissolution.
Featuring a selection of approximately 25 works from 2014–2015, the exhibition revisits a significant chapter in Passeri’s artistic journey, where vibrant colours, fluid compositions and layered textures evoke the emergence of life from primordial matter.
Moving between abstraction and organic forms, AB ORIGINE reflects on the fragile balance between nature, existence and time, inviting viewers to contemplate a fundamental paradox: every ending carries the possibility of a new beginning.
The exhibition opens on Friday, 20 November 2026, at 6:30 pm, as part of Art Evolution, hosted by Generali Perugia Settevalli in Perugia, Italy.
