Australia House is a Belle Époque‑style landmark on the Strand, designed by Alexander Marshall Mackenzie and built from 1913 to 1918 as the first major public building of the new Commonwealth of Australia. Opened by King George V, it is the oldest continually occupied diplomatic building in London and serves as the Australian High Commission. The marble‑lined Exhibition Hall, with its soaring columns and chandeliers, doubled as Gringotts Wizarding Bank in the Harry Potter films, though the hall is usually reserved for official functions. The building is an architectural jewel and a symbol of enduring kinship between Australia and the United Kingdom. Visitors cannot enter, but weekday glimpses through its glass doors reveal the opulent banking hall where goblins once welcomed wizards on screen. In *Harry Potter and the Philosopher's Stone* (2001), the bank's marble hall was filmed inside Australia House: Harry and Hagrid walk past rows of goblin clerks to access Harry's vault in Gringotts. The interior briefly returns in *Deathly Hallows Part 2*, when Harry, Ron and Hermione (disguised as Bellatrix and a bearded wizard) break into Bellatrix Lestrange's vault and escape on the back of a dragon; the dragon smashes the ornate chandeliers and ceiling as the trio flee. For the destructive scenes the filmmakers built an exact replica at the Warner Bros. studios to avoid damage to the real building.

Operated by West Coast Railways since 1995, the Jacobite steam train takes passengers on an 84‑mile return journey from Fort William to the fishing port of Mallaig. The route hugs the shores of Loch Eil, crosses the 21‑arch Glenfinnan Viaduct with views to the Glenfinnan Monument and Loch Shiel, skirts the white sands of Morar and terminates at Mallaig harbour. The service has become the company’s most successful line thanks to Harry Potter fans. On board, passengers ride in vintage carriages, visit the buffet car for refreshments and hear the hiss of a coal‑fired locomotive that evokes bygone travel. The maroon‑liveried carriages of the Jacobite became the Hogwarts Express in the films, carrying students to and from school. Shots of the train puffing across the Glenfinnan Viaduct are iconic, appearing in every film from *Philosopher’s Stone* to *Deathly Hallows* and capturing the excitement of the journey to Hogwarts. Scenes such as Harry and Ron’s first meeting, the Dementor attack and the trio’s return after the Triwizard Tournament were all filmed inside these carriages. The real‑life journey offers the same views seen on screen, from loch shores to heather‑clad mountains.

Shaftesbury Avenue is a major thoroughfare in London's West End, running from Piccadilly Circus to New Oxford Street. Built by the Metropolitan Board of Works between 1877 and 1886 and named after the 7th Earl of Shaftesbury, it cuts through the heart of the theatre district with iconic venues such as the Lyric, Apollo and Gielgud theatres lining its route. The avenue's mix of Victorian façades and modern storefronts make it a bustling cultural artery by day and an illuminated entertainment strip by night. Close to Piccadilly Circus and Soho, it is one of the West End's most recognisable streets. In *Harry Potter and the Deathly Hallows – Part 1* the trio apparate out of Bill and Fleur's wedding into the chaos of Piccadilly Circus and end up running along Shaftesbury Avenue. They narrowly avoid a No. 19 bus, press themselves against the railings outside the GAP store and pass grey stone columns while catching their breath. Ron gasps 'Where are we?' and Hermione replies 'Shaftesbury Avenue'. The scene captures the characters' disorientation amid everyday London traffic and landmarks.
