The Scottish National Portrait Gallery will re-open following redevelopment in Autumn 2011
The Scottish National Portrait Galley is to receive funding of £2 million from The Monument Trust.
The money will go towards its Portrait of the Nation project, which will transform the Gallery over the next two years.
"Their generous contribution puts us within reach of our £17.6 million target and brings us much closer to realising the ambitious plans we have for the Gallery," said James Holloway, Director of the SNPG.
The Portrait of The Nation project will help to repair, conserve and expand the SNPG by 50%.
The new spaces will be used to display their collection within five key areas; Reformation, Empire, Enlightenment, Modernity and Contemporary.
A permanent gallery for the Scottish National Photography Collection is also included in the redevelopment plans.
The Gallery was originally opened in 1889 and was the first purpose-built national portrait gallery in the world.
The building itself stands on Queen Street, in the heart of Edinburgh, and is an example of sandstone gothic architecture, modelled on the Doges Palace in Venice.
The Gallery closed its doors on November 2 2009 and is due to re-open in Autumn 2011.
