Tattenham Corner is a special place where people go to watch horse races. It's like a really big playground for horses and the people who like to watch them run fast.
You know how when you race your friends on foot, there's a finish line at the end? Well, horse races have a finish line too, and Tattenham Corner is in the middle of the track that the horses run on before they get to the finish line.
This corner is special because it's a bit tricky for the horses to run around. There are lots of turns and twists, and it's a bit like running around a maze. Sometimes the horses get a bit confused and have to slow down, so the jockeys who ride on top of the horses have to be very good at guiding their horse around the corner.
People who like to watch horse races like to go to Tattenham Corner because they can see all the horses running towards them before they have to turn the corner. It's like watching a really exciting scene in a movie - you don't know who's going to win until they get to the finish line.
So basically, Tattenham Corner is a really cool place where people go to watch horses run fast and turn corners like in a maze. It's part of a big horse racing event and lots of people love to go there and cheer for their favorite horse.
