Wimbledon gets pretty busy when the 2-week Grand Slam tennis tournament is in session. But when it's over, you might be able to grab a backstage pass for a behind-the-scenes tour.

Visitors get to walk right onto Center Court where every Men's and Women's final has been played since 1922.

Muggles might notice similarities to Goodwins Court and the fictional "Diagon Alley" in the wildly popular Harry Potter series. The hidden alleyway in Central London dates back to the 1600s.

Another stop on the Harry Potter tour? Bull's Head Passage, located in Leadenhall, which served as the entrance to the "Leaky Cauldron."

Davenports is believed to be the real-life "Flourish & Botts," where Harry Potter wizards would get school supplies for "Hogwarts School of Witchcraft and Wizardry."

Davenport's is the oldest family-run magic shop in the world, currently owned by Bill Davenport.

Hidden under the Charring Cross tube station, just finding Davenports requires a little magic.

Richard Jones, a Harry Potter expert, guides us to Watkins Books.

Fans who stop in the British bookshop can buy Dragon Powder among other memorabilia.

There is history all over London, but some of it is literally buried, including Winston Churchill’s War Rooms beneath the Treasury building in the Whitehall area of Westminster.

The military bunkers exist deep underground because they were built to protect England's War Department from getting bombed by Nazi Germany. They also served as the inspiration for the White House Situation Room.

Now you can tour the very place that Winston Churchill, England's most legendary Prime Minister, fought WWII and changed history.
