The French Tennis Federation has finally been given the go-ahead to redevelop Roland Garros.
The FFT announced plans in 2013 to expand the site of the French Open but has been mired in a long-running legal battle with opponents.
The controversy centres on a new court to be built in the neighbouring botanic gardens, where there are a number of historic greenhouses.
But the FFT announced on Thursday that final appeals by environmental groups and local opponents had been rejected.
The work, which includes a retractable roof over the main court, Philippe Chatrier, is expected to be completed by 2020, two years later than originally planned.
