Roland-Garros, which dates back to 1891, is the only one of the four major pro tennis tournaments — also known as Grand Slams — held on clay, a pretty tough surface to play on.
Named after a French World War I fighter pilot and aviator, Roland Garros is typically held in Paris in the springtime.
I’ve never been to the French Open, as it’s called, but in general, the crowds at Roland-Garros and Wimbledon are known for being more formal, with stricter etiquette for viewers. Meanwhile, the US Open has a more festival vibe, where it’s more acceptable for crowds to get in on the action with boos and cheers.
