What is the name of the neoclassical building in London that houses the Royal Academy of Arts?

The neoclassical building in London that houses the Royal Academy of Arts is Burlington House.

Burlington House stands on Piccadilly in Mayfair and is best known today as the Royal Academy’s London home. The Royal Academy moved there in 1868, a century after its foundation, after earlier premises—including space at Somerset House and the National Gallery—became unsuitable or too cramped.

The building began as a private mansion in the 1660s. Richard Boyle, 3rd Earl of Burlington, later transformed it in the Palladian manner with architect Colen Campbell and designer William Kent. Its architecture is therefore more precisely described as Neo-Palladian, a British form closely related to neoclassicism.

The Royal Academy occupies the main block, while learned societies use the surrounding wings. This explains a frequent confusion: the National Gallery and British Museum are also major London cultural institutions, but neither is the Royal Academy’s home. Burlington House remains a working arts and sciences complex, not just an exhibition venue.
