An elaborate 'Harry Potter' festival happens every year in this small town - here's what it's like

Each year, the small Philadelphia suburb of Chestnut Hill undergoes a magical transformation.

The Hogwarts Express rumbles into town, and Muggles set off to find hidden horcruxes, snack on chocolate frogs, and experience the wonderful world of wizards for themselves.

We're talking about the annual Harry Potter Festival. 

It all began six years ago, when Chestnut Hill College held a Quidditch Tournament on their campus. The castle-like school buildings are reminscient of Hogwarts, while quaint Chestnut Hill neighborhood (established in the late 1800s) makes for the perfect Hogsmeade replica. 

"There was a real interest in Harry Potter," Martha Sharkey of the
Chestnut Hill Business District told Tech Insider. "Fans really span generations."

The smash hit tournament spawned a larger festival.

"After the first year, the Chestnut Hill business community partnered with the college and created the festival," Sharkey explained. "This is the fifth year for the festival as a whole."

Everyone from toddlers to 40-somethings flock to Chestnut Hill to enjoy the elaborate event. Shops are renamed, selling Harry Potter themed merchandise and featuring interactive booths. There are character impersonators, live book readings, and even a "Wizard Rock" concert.
