Quick Answer
Where was Harry Potter filmed? Interiors such as the Great Hall were built as sets at Leavesden, near Watford, and the films also used real places: Alnwick Castle, Durham Cathedral, Gloucester Cathedral, Lacock Abbey, Oxford’s Bodleian and Christ Church, Leadenhall Market and Glenfinnan Viaduct. Not everything was shot in the UK. Opening details below are 2026 figures, so check before you travel.
Key Takeaways
- Most real locations are working places. The Bodleian’s Duke Humfrey’s Library can only be entered on a guided tour, and Durham’s Chapter House is closed on some dates for services and events.
- The Warner Bros. Studio Tour is the only place to see the original sets. It must be booked online in advance, and Visit London listed adult tickets from £108.75.
- Several popular claims could not be confirmed from official pages, including the New College ferret scene, which classrooms were filmed at Lacock, and whether Duke Humfrey’s has a restricted section scene. Where we could not confirm something, the article says so.
Where was Harry Potter filmed in real life
No single place stands in for Hogwarts. The films combined studio sets with castles, cathedrals, colleges and a railway viaduct, and the pages we checked name different buildings for different scenes. This table shows what each source says was filmed there.
| Place | What was filmed (per the source) | Where |
| Alnwick Castle | Hogwarts exteriors in the first two films, including the first broomstick lesson | Northumberland |
| Durham Cathedral | Professor McGonagall’s classroom in the Chapter House; Hedwig released in the cloisters snow scene | County Durham |
| Gloucester Cathedral | Hogwarts corridors, the Common Room entrance and the troll scene | Gloucestershire |
| Lacock Abbey | Parts of Hogwarts in two films, including the cloisters | Wiltshire |
| Bodleian Library | The Divinity School as the infirmary; the library scene in Duke Humfrey’s | Oxford |
| Christ Church | The staircase and entrance scene | Oxford |
| Leadenhall Market | Diagon Alley and the Leaky Cauldron entrance | London |
| Glenfinnan Viaduct | Seen in the films; the train is known as the Hogwarts Express | Scottish Highlands |
London
Leadenhall Market, Australia House and the bridges
Leadenhall Market says part of Harry Potter and the Philosopher’s Stone was filmed there in 2000 to 2001. Its roof and lanes appear as Diagon Alley, and Bull’s Head Passage was used for the Leaky Cauldron entrance, according to Visit London. Visit London also says Australia House’s interior was used for Gringotts, and that the Millennium Bridge was destroyed in Harry Potter and the Half-Blood Prince. The bridge is free to visit. Borough Market is listed as a filming location, but the page does not say which scene.
King’s Cross and Platform 9¾
Visit London calls the luggage trolley photo spot at King’s Cross one of the most famous moments of the series. It does not say which scene was filmed there, and it does not say whether the photo or the shop is free or how long the queue is. The station is free to enter and was listed as open Monday to Saturday 8am to 10pm and Sunday 9am to 8pm.
Oxford
Christ Church College Oxford Great Hall vs Hogwarts
Experience Oxfordshire says Christ Church’s Tudor dining hall “was used as an inspiration” for the Hogwarts Great Hall, and that its staircase was used for the entrance scene where Professor McGonagall meets the first-years. Christ Church’s own page says the staircase has appeared in Lewis and Harry Potter, without naming the scenes. Visit London says the Warner Bros. Studio Tour includes the Great Hall set, so our reading is that the Great Hall on screen was a studio set and the college hall was the inspiration, not the location.
Christ Church tickets are timed, and the college says booking online guarantees entry. Prices were not on the pages we read. The Picture Gallery closed for renovation from 30 April 2026.
Bodleian Library Duke Humfrey’s Library Hogwarts restricted section
The Bodleian says the Divinity School is the infirmary in the Harry Potter films. It is open daily and needs a ticket, which can be a self-guided visit or a library tour. Experience Oxfordshire says the scene where Harry walks through the library under his invisibility cloak was filmed in Duke Humfrey’s Library.
None of the pages we read mention a restricted section, so we cannot confirm one. Duke Humfrey’s is a working library. The Bodleian lists 30-minute and 60-minute guided tours as the way in, and Experience Oxfordshire says it is only accessible with a private tour. Tour prices were not shown on the pages we read.
New College Oxford tree Malfoy turned into a ferret scene
Guides often place the Goblet of Fire scene where Malfoy is turned into a ferret in the New College cloisters, and some mention a tree. We found no primary source for this: the New College and Experience Oxfordshire pages we could open did not mention it, so treat it as a widely repeated claim that still needs checking. We also did not find New College’s opening times or admission.
Oxford University Harry Potter filming spots tour
Several operators sell Harry Potter walking tours of Oxford, and listings appeared in our searches. We did not check their prices, routes or whether they include college entry. The Bodleian offers its own library tours and Christ Church offers guided tours with a Custodian or Cathedral guide, bookable through the college. Confirm what a tour includes before paying.
Scotland
Glenfinnan Viaduct and the Jacobite steam train
The Glenfinnan Viaduct appeared in the Harry Potter films. One fan site, jacobitetrail.co.uk, says the train’s official name is the Jacobite, and that “Hogwarts Express” is the fictional name. The service runs from Fort William to Mallaig, about 84 miles, and takes about 2 hours 10 minutes each way. That site gives the viaduct as 21 arches, completed in 1901 and 416 metres long.
The same site lists approximate 2026 fares of £55 to £60 for a standard adult return and £82 to £90 for first class, and advises booking well in advance. It gave the 2026 season as 1 June to 23 October, while its page title said 6 May to 31 October. We cannot resolve that conflict, and it said nothing about 2027. News reports have warned fans to stay off the tracks at the viaduct, so watch from the public viewing routes.
Elsewhere in England: the castle, cathedrals and abbey
Which castle was used for Hogwarts in the movies
No single castle. The films used several. Alnwick Castle stood in for Hogwarts in the first two films, according to its own website, and cathedrals and an abbey supplied interiors. We found no primary source naming one building as the whole of Hogwarts.
Alnwick Castle Harry Potter broomstick flying lessons
Alnwick’s website says Harry’s first flying lesson and Quidditch training were filmed in the Outer Bailey, and the Weasleys’ flying car crash in the Inner Bailey. Broomstick training is described as perfect for families and “available on many visitor days”. The page gave no price, age limit or dates, and said free timed tickets may be required on arrival. We did not find opening times for the castle.
Durham Cathedral chapter house Professor McGonagall’s classroom
Durham Cathedral says the Chapter House was used as Professor McGonagall’s classroom in the first two Harry Potter films. A cathedral article of 16 November 2021 adds that Harry releases Hedwig in the snow in the cloisters. The Forbidden Corridor was filmed in the triforium, which is not open to the public.
The Chapter House is open to visitors, 10am to 4pm, Monday to Saturday. There is no fee, but the cathedral asks for a £5 donation per person. Some dates are excluded because of services and events.
Gloucester Cathedral cloisters Harry Potter scenes
Visit Gloucester (8 November 2021) says that in Philosopher’s Stone, the South Cloister doubles as the Hogwarts corridors, the West Cloister Door is the Common Room entrance, and the Lavatorium is where Harry and Ron hide from the troll. It says the cathedral appears in three films but names only the first. The cathedral’s own what’s-on page has listed a cloister tour with afternoon tea, though we did not open it and have no date or price. We did not find the cathedral’s admission details.
Lacock Abbey Wiltshire Harry Potter corridors and classrooms
The National Trust says Lacock Abbey has stood in as parts of Hogwarts for two Harry Potter films, and for Fantastic Beasts: The Crimes of Grindelwald in 2017. It mentions the medieval cloisters. The pages we read did not name the corridors or classrooms used, so we do not list them.
The National Trust page listed cloisters hours of 10.15am to 4.45pm and abbey rooms from 10.30am, with last entry at 3.45pm. It gave two price tables without labels. Adult prices without Gift Aid were £21.00 in one and £14.00 in the other, and the page did not say which covers what. The Hither Way car park is less than 400 metres from reception.
Studio tour
Warner Bros. Studio Tour London Leavesden tickets
Visit London says the tour is at Leavesden, Watford, and that tickets must be booked online in advance, with none sold on the door. It listed adults from £108.75, children from £45.00 and families from £417.60, with infants free. The first tour starts at 9am and the last runs between 4pm and 6.30pm, depending on the season. Allow three to four hours. The listing is undated and the studio’s own site was unavailable to us, so check current prices. The listing also gave a London SW1 address that cannot be right for Leavesden, so use the official address.
Can you visit the actual Harry Potter film sets
Yes, in two ways. The studio tour has the original sets, including the Great Hall, Diagon Alley and Platform 9¾, per Visit London. Real locations such as Durham, Alnwick and the Bodleian are separate visits with their own tickets.
Was Harry Potter filmed entirely in the UK or a studio
Neither. The sets were built in a studio and real locations were used. One scene also left the UK: the Irish Road Trip (18 December 2025) says the Half-Blood Prince cave scene combined Ireland’s Lemon Rock with the Cliffs of Moher using CGI, with the outside of the cave real and the inside a set. We found no other overseas locations, but did not search for them systematically.
Planning
| Place | Entry detail found | Check before going |
| Alnwick Castle | Free timed tickets may be needed; broomstick training “on many visitor days” | Price, ages, opening times |
| Durham Chapter House | Free, £5 suggested donation; 10am to 4pm Monday to Saturday | Excluded dates |
| Lacock Abbey | Two adult bands, £14.00 to £21.00 | Which price applies, season dates |
| Bodleian | Divinity School ticketed; Duke Humfrey’s by guided tour | Tour prices |
| Christ Church | Timed tickets | Price, tour options |
| Studio tour | Adults from £108.75, book in advance | Current price |
| Jacobite train | About £55 to £60 standard return | 2027 season and fares |
Our suggestions, as editorial judgement: keep Oxford to one day, since the Bodleian tour and Christ Church tickets are the two bookings most likely to fix your timings. Treat Alnwick and Durham as separate days out, and book the studio tour before choosing a hotel, because it sells by slot. Remember that the cathedrals and the library are working places, so dress and behave accordingly.
