The Reptile House exterior along Regent’s Park paths stands as a brick-and-iron gateway that calls to mind London Zoo’s early 20th-century architecture. Its sturdy brick walls, archway entrance, and wrought-iron details create a cinematic backdrop that has drawn filmmakers and visitors alike. Built to house the zoo’s reptile collection, the facade carries a quiet, almost ceremonial air that contrasts with the park’s greenery and changing light. In the Harry Potter universe, the location has served as a recognizable establishing shot, pairing urban nature with a hint of magic just beyond the gate.

Completed in 2002 and designed by Foster + Partners, London City Hall is a bulbous glass‑and‑steel structure on the south bank of the Thames near Tower Bridge. Its asymmetrical form features a helical ramp spiralling through the interior and was conceived to minimise energy consumption. The building housed the Greater London Authority until 2021 and stands alongside the Shard and HMS Belfast on the riverside promenade. The public can view the exterior from the More London plaza, where fountains and seating provide river views. City Hall is sometimes claimed to appear during the Order’s broomstick flight along the Thames in *Harry Potter and the Order of the Phoenix*. The sequence shows the wizards soaring past Canary Wharf, HMS Belfast and Tower Bridge, but the bulbous silhouette of City Hall is not clearly visible. Consequently, there is no verifiable evidence that it appears in the films; this entry is marked for manual review.

St Pancras Renaissance Hotel’s exterior is a masterful display of Gothic Revival architecture, born from the 19th-century vision of the Midland Grand Hotel designed by George Gilbert Scott. After decades of neglect, the red-brick towers and ornate stonework underwent meticulous restoration and reopened as a luxury hotel in 2011, proudly framing the approaches to King’s Cross and St Pancras stations. The façade blends railway heritage with Victorian opulence, radiating a sense of grandeur that invites both travelers and photographers to linger. Its cinematic mood and location beside one of London’s busiest hubs have made it a familiar icon in popular culture, particularly within the Harry Potter fandom.
