Several areas of London will be illuminated over the next few days as a series of light installations take over the capital.
More than 50 works by UK and international artists are being displayed as part of Lumiere London.
In 2016, the event attracted more than 1.3 million visits to the West End, Mayfair and King's Cross.
Organisers have increased the footprint of Lumiere for 2018, with installations in areas including Westminster, Waterloo and Trafalgar Square.
On the South Bank, 40 luminous triangles form an interactive walkway.
Westminster Abbey has also been brought to life thanks to an impressive colourful projection.
Nearby, a giant projection has been blasted onto Westminster City Hall. It shows residents climbing up the walls. Its designer hopes it shows people how we can overcome overcome obstacles in our lives.
Lumiere London runs until Sunday, there are more details here.
