Inside Tower Bridge: Walk the Glass Floor and see the mechanical genius

Your journey begins with an ascent into the North Tower, which focuses on the challenge of building a movable bridge on the Thames.

• Immersive exhibits: Explore interactive displays, archival photographs, and films detailing the 8-year construction project, the massive workforce of 432 men, and the original designs submitted to the committee.
  
• Why it matters: Learn how Sir Horace Jones and Sir John Wolfe Barry designed the bascule mechanism, the key to solving the river traffic problem. 

Connecting the two towers 42 meters above the river, the high-level walkways are the undisputed highlight of visiting Tower Bridge.

• The Glass Floor: Step onto the Glass Walkway panels to look directly down onto the road, river traffic, and pedestrians below. 
  
• Panoramic vistas: Take advantage of the wide-angle views of London. Look east toward Canary Wharf and west toward the Tower of London, St. Paul's Cathedral, and the Houses of Parliament.
  
• Pro-tip: Time your visit using the official lift schedule. Watching the bascules rise directly beneath the glass floor is an unforgettable experience inside Tower Bridge.

After crossing the walkways, descend through the South Tower, which focuses on the people and maintenance of the landmark.

• Staff exhibits: Discover the stories of the people who have maintained and worked inside Tower Bridge since 1894. Exhibits include original tools, staff uniforms, and designs of the bascule chambers.
  
• Why it matters: This section connects the architecture to the hundreds of individuals, from watchmen to tracers, who kept the complex Victorian machine running daily.

Upon exiting the South Tower, you follow a unique feature: a blue line painted on the pavement that leads directly to the Engine Rooms.

• The memorial: The Blue Line is a short path embedded with bronze plaques, each commemorating the unsung heroes who built and operated the bridge. Look for the names of riveters, stokers, and even Hannah Griggs, the cook.
  
• Hidden gem: Created in 2016 in collaboration with local students, this feature is a metaphor for the link between the bridge’s past and present, ensuring the workforce remains part of the narrative inside Tower Bridge.

After crossing the walkway, descend to the base of the South Tower to visit the historic Engine Rooms, the Tower Bridge Museum's final essential stop.

• Steam engines: See the original preserved coal-fired engines, boilers, and six huge hydraulic accumulators that once powered the bascules. These machines were the beating heart inside Tower Bridge until 1976.
  
• Interactive demonstrations: Use hands-on models and informational panels to understand the genius of the Victorian hydraulic system, including how pressure was generated and stored to lift the 1,100-ton bascules reliably.
