Lancaster House is a grand Regency era mansion on Pall Mall, renowned for its sumptuous interiors and stately atmosphere. Though the house itself is privately owned and not open to visitors, its luxurious rooms have been used on screen to double as Buckingham Palace interiors, lending Bridgerton’s court scenes a tangible sense of royal opulence. The Music Room and surrounding spaces evoke the hush of a palace ballroom with gilded panels, crystal chandeliers, and carefully curated plasterwork that capture the drama of high society and political ceremony. Visitors primarily glimpse the exterior and the grand façades, while official events inside hint at the palace’s storied role in state life.

Historic mansion used as Buckingham Palace interiors in Bridgerton; not open to visitors.

Lancaster House stands as a commanding example of London's aristocratic architecture, a neoclassical-palladian mansion on The Mall that exudes imperial gravitas. Built in the early 19th century for the Leveson-Gower family and later acquired by the government, it has since hosted diplomatic events, state functions, and high-society receptions. Its red-brick façade, grand columns, and stately steps create a cinematic aura that has made it a beloved stand-in for Buckingham Palace interiors on screen. Although public access is limited, the exterior conveys a sense of secrecy and majesty, inviting visitors to glimpse a world of royalty and ceremonial pomp from a safe distance. The atmosphere blends historical prestige with cinematic possibility, especially when bathed in the soft glow of the London light.
