HUNDREDS of Harry Potter fans have been clamouring to explore the wizarding wonders in Oxford.

The release script of the West End play of the eighth instalment of the franchise – Harry Potter and the Cursed Child – has "reinvigorated" interest in all things magical according to a tour group..

The Harry Potter Tour, which sees young Muggles taken around the Oxford locations where the movies were filmed, has seen a "huge increase" over the last few weeks, said Oxford Footprints guide Charlie Dennis.

Indeed, the popular activity recently had a record breaking number of Potter fans partake in the wizarding walkabout.

Mr Dennis said: "We had 2,000 people in one week. Generally, we’ll do one to two Harry Potter tours a week, but if you look now you’ll see they’re all booked up."

Visitors weave their way to Divinity Hall, New College, and Christ Church – the latter used to film the great hall scenes at Hogwarts School of Witchcraft and Wizardry.

Participants also discover how Harry Potter is intertwined with Oxford University as well with Mr Dennis, a recent graduate himself, explaining how there is a Harry Potter Society as well as two Quidditch teams, one of which recently headed to Italy for the world championships.

The Cursed Child play, which is only performed in London’s Palace Theatre but is rumoured to go on tour, has been an instant hit selling out in minutes.

Its script was released on July 31 and has since sold over three million copies worldwide, making it the best selling script in recorded history.

The Harry Potter hysteria has seen a renewed interest in books according to the city's Blackwell’s bookstore, which has reportedly sold nearly 800 copies of The Cursed Child script since its release.

The newest instalment has "completely reinvigorated" interest in the series, shop manager Rebecca Macalister said.

She added as well as book sales, the shop had also seen an increase in merchandise sales with potty Potter fans pouring in to purchase memorabilia such as wands, games, and bookmarks.

When asked if interest could to wane following the end of the series, Ms Macalister said she believed it would "very much endure".

She added: "They’re timeless classics, they don’t fade."
