Room A, as it was formerly known, was built in 1975 and used to store paintings for show on the main-floor galleries.
Following a two-year refurbishment programme, it is now opening to the public as Gallery A, and will show a wide selection of paintings from the 13th to late-19th centuries.
The space has been developed by architect C.F Møller, which worked with the National Gallery’s design team on the project.
The artworks are divided into three sections – Renaissance, Baroque and post-1800 – and works by Botticelli, Emile-Jean-Horace Vernet and the Barbizon School are featured.
The National Gallery says, ‘This newly reopened space will aim to increase visitors’ appreciation and understanding of some of the gallery’s lesser-known paintings and provide the space and opportunity to study these works in greater detail than before.’
