Workers have begun painting the Lincoln Memorial Reflecting Pool blue as part of US President Donald Trump's bid to beautify Washington DC ahead of the nation's 250th birthday this summer.
The historic pool, stretching 2,030ft (620m) between the Lincoln Memorial and the Washington Monument, has long been plagued by leaks, structural deterioration, faulty pipes, algae growth and bird droppings.
Trump has said his project to restore and paint the monument would solve the leaking problem and make the pool more beautiful than ever.
But it is unclear whether the repairs can specifically fix the underlying structural issues at the attraction, which was built in 1922.
The reflecting pool was "filthy, dirty, and it leaked like a sieve for many years", Trump said in a video message from the Oval Office in April.
