At which famous London gallery does Mr. Bean work as a security guard in Bean?

In the film Bean, Mr. Bean works as a security guard at London’s National Gallery.

The National Gallery setting establishes the film’s central contrast: Mr. Bean is placed near priceless works of art despite being comically unsuitable for formal responsibility. His apparent incompetence eventually becomes part of the plot when he is sent to the United States as an expert associated with Whistler’s painting Arrangement in Grey and Black No. 1, commonly called Whistler’s Mother.

The National Gallery is a real museum on Trafalgar Square in London and is separate from Tate Modern, another major London art institution. The film’s fictional events should not be mistaken for a claim that the real gallery employed Rowan Atkinson’s character.

This setting also explains why the movie’s humor repeatedly involves museum etiquette, conservation, public viewing, and the tension between artistic prestige and Bean’s chaotic behavior.
