Big Ben

The Elizabeth Tower houses five bells, with the 13.7-ton Great Bell (Big Ben) chiming the hours while four quarter bells play the Westminster Quarters every fifteen minutes. You're looking at 316 steps spiraling up cast iron stairs, passing the Ayrton Light that glows when Parliament sits at night, and reaching the belfry where the mechanism that's kept London punctual for over 160 years still operates with Victorian precision.

The 90-minute tour moves through narrow stone corridors and up increasingly steep staircases. Your guide explains how the pendulum swings in a vacuum case and why they add old pennies to adjust timing. The highlight is standing beside the Great Bell when it strikes - the vibration travels through your chest. The clock faces, each 23 feet across, look surprisingly small from inside, and the view from the top spans from Canary Wharf to Windsor Castle on clear days.

Only UK residents can tour inside, and you need your MP to request tickets months ahead - it's genuinely exclusive, not tourist theater. The scaffolding finally came down in 2022 after five years of restoration, so exterior photos are perfect again. Skip the expensive Westminster Abbey combo tickets nearby; Big Ben's real magic is hearing those bells up close, not posing outside with every other visitor.
