The renowned Art Gallery of Ontario (AGO) is one of the largest museums in North America. The collection of more than 95,000 pieces includes works from around the world, from European masterpieces to contemporary art, but also holds an impressive collection of Canadian Art, including a vast collection of works by the Group of Seven. A series of temporary exhibitions are mounted throughout the year. The AGO occupies a unique looking building, with a mix of older and modern architecture, on the west side of the city center. Next to the AGO is the hard to miss Ontario College of Art and Design, standing high above the street on stilts designed to look like pencils.
