British Museum

When Robert Smirke designed the British Museum in 1823, he envisioned a temple of knowledge with perfect neoclassical symmetry, 44 Ionic columns marching across the facade. Yet while millions flock annually to the grand south entrance with its monumental steps and pediment, the rear entrance on Montague Place remains quietly elegant and largely forgotten. This second door to the world’s first national public museum, founded in 1753, offers the same classical colonnade but without the crowds, a backdoor to eight million objects spanning human history.

Smirke’s south front took nearly thirty years to complete, not out of design trouble but because the museum couldn’t afford to close while it was being built around itself. The Montague Place entrance came later, functional rather than ceremonial, built for staff and deliveries rather than triumphant arrivals. It has since become the museum’s best-kept secret: the same architectural ambition, the same free admission, the same eight million objects, minus the queue that wraps around Great Russell Street every morning. Smirke built one grand entrance and one honest one. History remembers the grand one.
