Two new entrances to the National Gallery have been unveiled as part of a £21m redevelopment.
The light-filled atrium is at the heart of the project
From Sunday, visitors to the gallery will enter the building from Trafalgar Square and St Martin's Place.
The Sir Paul Getty Entrance - on the north side of the square - takes people directly into the newly refurbished Central Hall.
The hall - which used to be a shop - is now home to eight paintings from the Italian Renaissance.
Gallery executives hope it will make the institution more open and welcoming.
The Sir Paul Getty Entrance - so-called following a £10m donation from the family foundation - leads into an atrium and a grand staircase against a black marble wall which takes visitors through to the hall.

The other entrance leads into the expanded and refurbished cafe from St Martin's Place.
An additional £4.5m is still needed to complete the second phase of the
redevelopment project, which includes knocking down the two dividing walls which
were a later addition in the Portico Entrance Hall.
The redevelopment of the East Wing will open to the public on Sunday.
