Frankenstein – The Signet Library

Guillermo del Toro’s 2025 Netflix adaptation of Frankenstein, starring Oscar Isaac as Victor Frankenstein, Jacob Elordi as the Creature, and Mia Goth as Lady Elizabeth, transforms Edinburgh’s historic Signet Library into a lavish ballroom for a pivotal social gathering. This neo-classical gem, nestled in the heart of the Old Town just behind the Royal Mile and Parliament Square, provided the elegant backdrop for scenes blending opulence with underlying tension. The library’s soaring ceilings, intricate plasterwork, and rows of leather-bound volumes evoke the grandeur of 19th-century high society, perfectly suiting the film’s Gothic atmosphere. Filming here captured the contrast between refined exteriors and the story’s dark undercurrents, drawing on the location’s real-world prestige as a venue for writers and legal scholars.

The Scene

In the film, the Signet Library hosts Frankenstein’s elegant ball, a key sequence where Victor and Lady Elizabeth share a supper and dance amid swirling gowns and candlelight. This moment highlights Victor’s strained family dynamics and budding romance, set against the library’s opulent dining room. Guests converse in hushed tones while dancers glide across the polished floors, but the scene foreshadows tragedy with subtle hints of Victor’s obsessive pursuits. The neo-classical architecture amplifies the formality, with chandeliers casting dramatic shadows that mirror the characters’ inner turmoil. Production notes describe it as a fine dining and dancing highlight, immersing viewers in a world of Regency-era splendor before the narrative descends into horror.

The Real Filming Location

The Signet Library stands as an elegant neo-classical building on Edinburgh’s Royal Mile, constructed in the early 19th century as the home of the Society of Writers to Her Majesty’s Signet, a prestigious legal body. Located at Parliament Square behind St. Giles’ Cathedral, it features two stunning reading rooms with barrel-vaulted ceilings, mahogany bookcases, and green leather armchairs that create an air of timeless scholarship. Beyond its daily function as a working legal library, it serves as a premier event space for weddings, corporate functions, and cultural gatherings. Its proximity to Edinburgh’s historic closes and squares made it ideal for seamless integration with exterior shots of the Royal Mile and Parliament Square, enhancing the film’s authentic Old Town feel.

Why This Location Was Chosen

Producers selected the Signet Library for its Georgian elegance and central Old Town position, which aligned perfectly with the film’s 1800s Edinburgh setting without revealing its modern surroundings. The neo-classical interiors offered a ready-made ballroom with authentic period details like ornate plasterwork and vast book-lined walls, minimizing set construction needs. Its location just paces from execution spots and winding closes added atmospheric depth, evoking the era’s macabre underbelly. Del Toro’s team appreciated how it blended seamlessly with nearby shoots on Parliament Square and Canongate, creating a cohesive urban backdrop. While specific director quotes are limited, the choice reflects a preference for versatile, historically resonant venues that amplified the story’s themes of intellect and isolation.
