Trafalgar Square has been transformed into a green space.
More than 2,000 sq m of turf has been laid as part of Visit London's campaign to promote green spaces and villages in the city.
The grass will cover the square for two days during which visitors will be able to soak up the sunshine in specially laid-out deckchairs or enjoy a picnic.
The turf, which has been sourced from the Vale of York, will then be moved to Bishops Park in Hammersmith and Fulham.
Chief executive of Visit London James Bidwell said: "From the rural feel of areas like Bexley Village and Wimbledon, to urban villages like Marylebone and even Canary Wharf, the campaign will help everyone discover Village London."
