Check out these photos from the Harry Potter studio tour which will open at a film studio near London at the end of March.
See Hogwarts itself in all its glory. Well - it's a model of course, but it's still pretty cool. It's part of a new exhibition: the Harry Potter Studio Tour at Warner Brothers Leavesden Studios, near Watford.

In Dumbledore's office you can check out all his wizard portraits - unfortunately there wasn't enough room for his phoenix, it was a bit of a fire hazard...

Up close, all of the goblin masks from the workers at Gringotts Wizarding Bank look pretty scary! The studios open to muggles on Saturday 31 March - but tickets are sold out for weeks.

Just because they're models doesn't mean they're not scary! Check out Aragog the spider - creepy!

The entrance to the Great Hall might look really old - but it's just another newly-built set like the rest of it!
