PARIS — Roland Garros keeps changing look and shape in the 21st century. It is vaster and more avant-garde, and perhaps it will become less crowded in the passageways as tennis fans shuffle from match to match.

The No. 1 Court, known as the bullring, will soon be demolished. The No. 2 Court, with its enchanting lack of symmetry, is already gone.

Even the main Philippe Chatrier Court, where Rafael Nadal won his 12th French Open singles title on Sunday, was reconstructed in the past year.

It might be hard to believe at this stage, but Nadal will fade from view someday, too. Or at least he’ll spend men’s final day in the front row of the presidents box, his water bottles surely still in order, instead of in the arena with his socks coated in red clay and his poor opponents failing to find, to use one of his favorite English words, solutions.
