I am not sure why the Changing of the Guard at Buckingham Palace is such a famous spectacle. Maybe it has something to do with the well known poem by A A Milne (author of Winnie the Pooh):
They’re changing guard at Buckingham Palace -
Christopher Robin went down with Alice.
Alice is marrying one of the guard.
A soldier’s life is terrible hard, – Says Alice.
Or maybe people are just curious to see men wearing tall, black, furry hats!
If you want to see the Changing of the Guard for yourself, it takes place daily at 11.30am from April thorugh to July and alternate days at 11am the rest of the year. Be warned though that it is frequently cancelled because of bad weather or other events.
Due to the popularity of the spectacle it is advisable to arrive at least an hour early to bag a good spot to watch from.
