UK's biggest Harry Potter shop to open in London

It sounds like something straight off the Marauder's Map - a huge new Harry Potter shop is appearing in the heart of London.

Warner Bros - the film studio behind the movies - says the store will be the biggest official Harry Potter shop in the UK and is due to open on 4 November on Oxford Street, one of London's busiest shopping streets.

It's certainly won't just be a tiny cupboard under the stairs. The shop will be the size of seven and a half tennis courts and is inside a new building on called The Ribbon.

Spread across two whole floors, fans will be able to move between different themed spaces, inspired by Diagon Alley, the hidden shopping street from the Harry Potter stories.

In the books and films, witches and wizards visit Diagon Alley to buy things like wands, robes, books and other magical supplies.

Warner Bros says visitors will be able to see a giant Ukrainian Ironbelly Dragon - the largest breed of dragon in the Wizarding World of Harry Potter - positioned above a Gringotts bank area. There will also be a full-sized Knight Bus.

The shop may sound like a treat for fans, but it could also be very busy.

Oxford Street already attracts around half a million visitors each day, so anyone hoping to visit may need patience, and perhaps a tiny bit of Felix Felicis luck.

It will be the second official Harry Potter shop in the UK, after the one at King's Cross Station.
