Join the Hidden London guided tour, where you'll explore a pivotal 1906 urban transformation.

Step through hidden doors into disused spaces that have been closed to the public for nearly three decades. Led by an expert guide, you'll visit the long-shut platforms of the former Aldwych branch line on the Piccadilly line.

See vintage posters on the walls, the original Edwardian design by Leslie Green, and an intact early 20th-century signaling cabin. This tour offers a unique look at the history of urban development.
