Firefighters have extinguished a blaze which broke out at the National Archives in Kew this afternoon (Saturday).
Two disused waters towers were on fire at the site in Richmond, which is home to some of the UK's most important historical documents, some dating back 1,000 years.
Crews from Hammersmith, Richmond, Kingston and Wandsworth - in total 20 firefighters - fought the fire after being called out at about 12:30pm. It was extinguished around an hour later.
A spokesman for the London Fire Brigade said: "Firefighters were called after a blaze broke out on Bessant Drive in Kew this afternoon. Crews tackled the blaze, which was affecting two disused water towers, and brought the fire under control quickly. No injuries were reported.
"The fire caused significant damage to the water towers and smoke could be seen from the surrounding area."
The National Archives is home to many secret government documents. There are 11 million historical documents stored there in total, including the Domesday Book.
A spokeswoman from the National Archives told the BBC everyone was evacuated from the building safely and no documents were damaged. The building is currently being closed to the public.
