Scottish National Gallery of Modern Art, Edinburgh

Modern Two, previously known as the Dean Gallery, is situated in Edinburgh and forms one half of the Scottish National Gallery of Modern Art, a major art institution in Scotland. Managed by National Galleries Scotland, it works in tandem with its counterpart, Modern One, located just across Belford Road.

The history of the building traces back to 1727, when Andrew Gairdner, a local merchant, established a facility for orphans. This structure, originally the Dean Orphanage, became the subject of an 1830 watercolour by Thomas Hamilton. Its construction, which took three years, used Craigleith stone from a nearby quarry. The building's English Baroque style incorporates classical elements, and its towers, which house chimneys, are a notable part of Edinburgh’s western skyline. Owned by the City of Edinburgh Council, the building served as the Dean Education Centre for many years before its transformation into a gallery.

The building's conversion into a gallery was overseen by Terry Farrell and Partners, and it opened in 1999 across from the existing Scottish National Gallery of Modern Art. In 2011, the two buildings were renamed as Modern Two and Modern One.

Modern Two is renowned for housing the Paolozzi Gift, a collection from Sir Eduardo Paolozzi, and also showcases an extensive array of Dada and Surrealist art and literature, largely donated by Gabrielle Keiller. Additionally, it hosts temporary exhibitions.

The gallery is encircled by a sculpture garden, displaying various modern and avant-garde pieces, such as William Turnbull's Gate (1972), George Rickey's Two Lines up Excentric VI (1977), and Emile-Antoine Bourdelle's La Vierge d'Alsace (1919–1921), among others.
