over the staircases contain chimneys and contribute to the Edinburgh skyline in the west of the city centre. The clock above the entrance comes from the original Orphan Hospital and in turn from the 1764 demolition of the Netherbow Port on the High Street, which formerly separated the High Street from the Canongate. The building, which is owned by the City of Edinburgh Council, served as the Dean Education Centre for many decades before conversion to a gallery. The plot of allotment gardens at the main entrance dates from 1940 when many school grounds were used for such purposes. Conversion to gallery The conversion of the building into a gallery was designed by the architect Terry Farrell and Partners. The gallery opened in 1999 opposite the existing Scottish National Gallery of Modern Art. In 2011, the buildings were rebranded Modern Two and Modern One, respectively.
