Step into the iconic sets like:

The Great Hall

Serving as the backdrop to some of the film series’ most iconic scenes such as the Yule Ball and the Battle of Hogwarts, the Great Hall was first built for Harry Potter and the Philosopher's Stone in 2000 and was used as a key set for six more films.

The Great Hall is home to some of the beautifully handcrafted props created for the Harry Potter film series including Professor Dumbledore’s lectern and the House Points Counter.

Forbidden Forest

The Forbidden Forest seen in Harry Potter and the Philosopher’s Stone was a location and studio shooting combination. This moved entirely to the Studio for Harry Potter and the Chamber of Secrets to house Aragog’s lair and continued to grow throughout the film series.

The Forbidden Forest seen on the Studio Tour is filled with 19 trees, each with over 12 feet.

Platform 9¾

The Hogwarts Express locomotive transported hundreds of students from Platform 9¾ to Hogwarts School of Witchcraft and Wizardry. Most of the scenes that take place on Platform 9¾ were actually shot on location at King’s Cross Station in London, however, during Harry Potter and the Deathly Hallows – Part 2, part of the station platform was recreated on a soundstage here at Leavesden, complete with the track and the train.

Diagon Alley

The Diagon Alley set constantly changed throughout the film series. Since its construction, walls have shifted, shop fronts have moved and entire buildings have been carefully tweaked, leaning just slightly, to create the street that is seen in the films. Many of the Diagon Alley set pieces were also re-dressed for use in the village of Hogsmeade for Harry Potter and the Prisoner of Azkaban.

Diagon Alley is home to not only Gringotts Bank, Flourish and Blotts, and Mr. Mulpepper’s Apothecary but also the dusty Ollivanders wand shop, where Harry’s wand famously chose him. During filming, the shop was home to more than 17,000 individually labelled wand boxes.

Props :

 Spot your favourite prop from the film:

Potions Classroom

Over 950 potion jars line the walls of the classroom, each with unique props kept inside them including baked animal bones from a local butcher shop, dried leaves, herbs, and shrunken heads made by the props department. Each jar features a label hand-designed by Graphic Design duo MinaLima.

Memory Cabinet

Nearly 900 memory vials and labels were created for the cabinet that can be found in Professor Dumbledore’s office. Each label was hand-designed by the Graphics Department before being sent to the Props team who would put the label into place on each vial.

Professor Umbridge's Office

Great attention was paid to the inside of the only pink office in the Ministry of Magic, belonging to Professor Dolores Umbridge, including her collection of plates featuring various moving kittens. Over 130 plates were created for the office which involved filmmakers having to photograph and film real kittens with crystal balls, witches’ hats, and balls of wool.

Puking Pastilles

Stocking everything from Extendable Ears to fireworks, Weasleys’ Wizard Wheezes was designed to look like an 18th-century storefront and took more than three months to build — and much of that time was spent constructing the 20- foot mannequin above the main entrance.

The Puking Pastilles dispenser that can be seen at the Studio Tour was created by Head Propmaker Pierre Bohanna and was designed to be funny and disgusting at the same time.

Special & Visual Effects (SFX & VFX) :

Chamber Of Secrets Door

Often mistaken for a Visual Effect, the Chamber of Secrets door is actually a fully operational door created by the Special Effects team based upon sketches provided by the Art Department. The articulated snakes slither along slotted tracks and are powered by an electric motor hidden behind the door. Each snake was individually cast in resin and painted before being attached to the door with careful thought so that each snake would retract at the precise time avoiding a collision.

Invisibility Cloak

Gifted to Harry in Harry Potter and the Philosopher’s Stone, the Invisibility Cloak features prominently in the films. The cloak that can be seen at the Studio Tour was created from special velvet fabric and printed Celtic symbols and ancient runes onto it by the Costume Department.

Whomping Willow

A full-sized tree trunk was built on set for the Whomping Willow’s appearance in Harry Potter and the Prisoner of Azkaban, with branches added digitally in post-production.

Green Screen

Don't miss out on the opportunity to take part in our green screen experience and fly a broomstick over London just like the cast did during filming.



Filmmakers faced a huge challenge when turning the wizarding sport of Quidditch into a real sport they could capture on film. In Harry Potter and the Half-Blood Prince, the Quidditch players were given modern tracksuit-style clothes for training sessions, and elbow, knee pads, and helmets were added to their match gear to reflect the violent nature of the sport.

Yule Ball

Costume Designer, Jany Temime designed over 300 costumes for the Yule Ball which required over 100 extra costume staff to help create. Creating Hermione’s iconic Yule Ball gown proved to be a daunting task for Temime.

A kind of ‘Wizard’s Tuxedo’ was created for the Hogwarts boys in satin silk while the Durmstrang students had military dress uniforms. Ron Weasley was the only exception with robes made from old carpet fabric and acres of lace!

The “French Blue” fabric of the Beauxbatons uniform was chosen to stand out from the muted blacks, browns, and greys of the other school colors. The iconic pointed Beauxbatons hat was designed and produced by renowned milliner Philip Treacy.

Creature Effects :

  1. A full-size practical Basilisk mouth was created by the Creature Shop to fight against in the final battle scene measuring up to 30ft long with jaws 3ft deep.
  2. Three life-size animatronic versions of Buckbeak the Hippogriff were created for the Harry Potter film series: one standing, another rearing, and a third lying down.
  3. Created by Nick Dudman, Creature and Make-Up Effects Designer, and his team, each Goblin was given a particular personality perceptible in their distinctive ears, chins, and noses to ensure they all looked different.
  4. Aragog had a leg span of over 18 feet and was even able to crawl out of a hole and deliver dialogue in Harry Potter and the Chamber of Secrets. Each of Aragog’s hairs was individually inserted by hand using a special needle using many different materials from brooms bristles and pieces of coconut to the centre of feathers.

Art Department :

Hogwarts Castle Model

The jewel in the crown of the art department is the intricately detailed model of Hogwarts castle. Built for the first film, Harry Potter and the Philosopher's Stone, the model's every courtyard, tower, and turret were filmed and enhanced with digital effects to create unforgettably realistic views of the magical school

To make Hogwarts appear even more realistic, artists rebuilt miniature versions of courtyards from Alnwick Castle and Durham Cathedral, where scenes from Harry Potter and the Philosopher’s Stone were shot.

Graphic Design

Graphic design duo MinaLima designed an array of props from Potions textbooks to wizarding sweet packaging and issues of the Quibbler. By the end of the Harry Potter film series, Graphic Design duo MinaLima had designed over 40 editions of the wizarding world newspaper, The Daily Prophet.

White Card Models

During the filming process, before the actual set construction began, the Art Department would create a white card model of the set/location. These models helped the director and production designer look at size and scale and determine camera angles.

Technical Drawings

Dozens of concept artists, illustrators, and art directors created every environment, prop, and character of the Harry Potter film series.

Led by Production Designer Stuart Craig, the Art Department designed 588 sets across the Harry Potter film series.
