Wimbledon The Championships, commonly known simply as Wimbledon, is the oldest tennis tournament in the world and is regarded by many as the most prestigious.

The French Open (Roland Garros) is the hardest Grand Slam to win for several reasons. The French Open is a clay court tournament, a physically and mentally demanding surface for players. The weather conditions can be unpredictable, and players are expected to play in windy and rainy conditions.

Grass courts are very expensive to maintain. That's the primary reason. There is currently a rather short 'grass court season', mostly in the UK, as the lead up to Wimbledon. There is one grass court tournament in the US in Newport, RI where the Tennis Hall of Fame is located.

In terms of history, Wimbledon is the most prestigious. Generally the Australian open is the least because it is only since the advent of long distance air travel and the open era that the event was entered by most players.
