Borough High Street has served as the main southern approach into London since Roman times. By the 1700s it was a chaotic thoroughfare; stalls and livestock from Borough Market clogged the only route into the city from the south until an Act of Parliament moved the market off the roadway. Today the street is lined with centuries‑old inns, railway arches and modern shops, leading visitors toward the bustling Borough Market. As one of Southwark's oldest streets it still conveys the gritty energy of London traffic and history, making it a natural setting for cinematic chases. In *Prisoner of Azkaban* the purple triple‑decker Knight Bus careens through Southwark before screeching to a halt outside the Leaky Cauldron on Stoney Street. Along the approaches to Borough Market it prangs a car and sets off its alarm, narrowly missing other vehicles. The surrounding streets provide the chaotic, urban backdrop for Harry's whirlwind arrival in the wizarding world.

Borough Market, London's oldest food market, has traded for more than 900 years. Originally held in the middle of Borough High Street, the market caused such congestion that an Act of Parliament in 1756 moved it off the road. Today its maze of stalls sits beneath railway arches, offering artisan produce and street food. The quiet corner at 7 Stoney Street houses a small shopfront that became a film landmark—the exterior of the Leaky Cauldron in the third Harry Potter film. Visitors browse under wrought‑iron canopies, passing florists, cheesemongers and bakers in a space that feels both timeless and vibrant. In *Harry Potter and the Prisoner of Azkaban*, the filmmakers relocated the Leaky Cauldron entrance from Leadenhall Market to Borough Market. After a wild ride on the Knight Bus, Harry disembarks outside a flower shop at 7 Stoney Street and walks through its door into the Leaky Cauldron. In the same sequence the Knight Bus screeches to a halt and prangs a car before stopping outside the pub and The Third Hand Bookstore. Only the exterior was filmed here; interior scenes were shot on a studio set.

Set along the River Thames on the East Bank, this promenade offers a wide, breezy vantage across the water and the City skyline beyond. The Millennium Bridge and its surrounding Thames Path are rich with modern-London vibes, blending foot traffic, river breeze, and distant city silhouettes into an unmistakable cinematic mood. The location has featured in establishing shots for films, underpinning stories with a vivid sense of place as the river slips past historic and contemporary landmarks. The atmosphere is open and cinematic, inviting quiet morning light, moody dusk hues, and the gentle sounds of water and footsteps along the pedestrian route.
