Toronto – Canada








In 2006, Emily and Mitch Rales opened their private museum, The Gallery, designed by the late New York architect, Charles Gwathmey, on their 230-acre Maryland property, where they also lived, in order to share their post World War II modern and contemporary art collection with the public.  The combination of Mitch Rales’ business acumen and great success in venture capitalism and Emily Rales’ art historian and gallery background soon created a vast collection that outgrew the confines of The Gallery. 


The Pavilions, a 204,000 square foot series of buildings, of which 50,000 square feet are gallery spaces, are connected by a glass-enclosed walkway and surround an 18,000 square foot water court filled with water lilies. This proved to be the answer to the lack of space and turned the museum into one of the largest private museums in the world.  The Glenstone’s $200 million expansion, designed by Thomas Phifer and Partners, consists of 11 galleries of brilliant works of art by such renowned artists as Louise Bourgeois, Keith Haring, Jenny Holzer, Jackson Pollock, Jasper Johns, Donald Judd, Alexander Calder, Kerry James Marshall, Yayoi Kusama, Dan Flavin, Agnes Martin, Henri Matisse, Mark Bradford, Damien Hirst, Martin Puryear, Mark Rothko, David Hammons, Andy Warhol, Robert Rauschenberg, and Cy Twombly, to name just a few.  Sculptor Michael Heizer has an outdoor, rooftop installation all to himself. The regularlyrotating exhibitions are all drawn from the Rales’ collection in the completely naturally-lit spaces of the buildings.


Landscape architects Adam Greenspan and Peter Walker of PWP Landscape Architecture designed stunning outdoor vistas that contain 7,000 trees, thousands of shrubs, annual and perennial grasses and flowers beside meadows, streams, paths, and along trails that all complement and accommodate magnificent sculptures by the likes of Richard Serra, Jeff Koons, Ellsworth Kelly, Felix Gonzales-Torres, Tony Smith, Robert Gober, and many others that can all be admired on the Glenstone’s sculpture tours. 


The Glenstone is a glorious experience both indoors and out.  It combines environment”.   Its superb art amidst magical surroundings presents a unique spiritual as well as an intellectual experience.  Four to six hours can easily be spent admiring the art, walking the grounds, taking breaks at the café for casual dining, and visiting the Glenstone’s Environmental Center.
