Westminster is a London Underground station in the City of Westminster. It is served by the Circle, District and Jubilee lines. On the Circle and District lines, the station is between St. James's Park and Embankment, and on the Jubilee line it is between Green Park and Waterloo. It is in Travelcard Zone 1. The station is located at the corner of Bridge Street and Victoria Embankment and is close to the Houses of Parliament, Westminster Abbey, Parliament Square, Whitehall, Westminster Bridge, and the London Eye. Also close by are Downing Street, the Cenotaph, Westminster Millennium Pier, the Treasury, the Foreign and Commonwealth Office, and the Supreme Court.

The angular steel and concrete design of Westminster Underground Station represents one of the most ambitious architectural undertakings of London’s Jubilee Line Extension, opened in 1999. Designed by Foster + Partners, the station descends more than 30 meters below ground beside the Houses of Parliament, requiring deep excavation and advanced structural engineering to stabilize the surrounding historic area.

The stairwell seen here showcases the station’s signature industrial aesthetic — exposed concrete ribs, perforated metal panels, and massive supporting beams that evoke the look of a subterranean cathedral of infrastructure. Built within a massive box excavated beneath Bridge Street, Westminster’s layout integrates vertical circulation through lifts, escalators, and these steep stairways connecting the ticket hall to multiple underground levels. The design not only accommodates heavy passenger volumes but celebrates the raw mechanics of public transit, merging utility with architectural expression.

The Jubilee Line platforms at Westminster Underground Station represent the deep-level engineering and modernist design of London’s late-20th-century transit expansion. Constructed as part of the 1999 Jubilee Line Extension, these platforms sit approximately 30 meters below ground, directly beneath the District and Circle line tunnels. Designed by Foster + Partners, the station features full-height platform screen doors — a safety innovation uncommon on most of the Underground — and a sleek system of acoustic panels and perforated aluminum cladding that enhance both sound control and visual uniformity.

Every structural and material detail reflects the project’s dual purpose: to manage immense passenger flow serving Parliament and Whitehall above, while preserving architectural clarity within a highly constrained urban site. The smooth curvature of the platform walls, precision lighting, and isolation of mechanical systems behind layered steel panels highlight the station’s integration of industrial functionality with the aesthetics of modern infrastructure.
