Yes. It was used for the first time in 2009.
As of 2009, there is a retractable roof on the Wimbledon center court.
The All England Club, where the Wimbledon Championships are played, does not play matches after 11pm. Most matches are finished by early evening, especially now the retractable roof has ended timely rain delays.
== == One hour The process takes 56 minutes and 30 seconds - and the roof should only be operated when the stadium is empty.
If the ball that is currently in play strikes any inanimate object, it is considered out, and so the opponent wins the point.

1877. The winner was W. Spencer Gore (1850 - 1906. The final was postponed from Monday 16 July to the following Thursday because of rain, which should never happen again due to the new roof over centre court. There were only two hundred spectators watching from a stand made of three planks of wood.
Most places don't have a roof because it's expensive. But if they do, they do use it when it rains. However, if it's not raining, they don't close the roof because it changes the court conditions. (Indoor tennis is different than outdoor tennis, yes.)
The one difference is that an arena has a roof.
