Tower Bridge

The most photographed bridge in London, Tower Bridge is a Victorian marvel that straddles the Thames just east of the City. Built in 1894, it's a proper engineering feat - that Gothic-style brickwork with the twin towers makes it unmistakable, even if you've only ever seen it in films. The bridge still raises its bascules for river traffic, which happens around ten times a day depending on boat schedules, so timing a visit to catch it is brilliant fun.

You can walk across for free - takes five minutes if you're just crossing, but most people linger mid-span to photograph the view upriver towards St Paul's Cathedral and down towards the Docklands. The paid exhibition inside the towers lets you explore the machinery, Victorian engineering, and high-level walkways between them. It's pricey and honestly, unless you're keen on mechanical history or want the elevated views, the exterior and free walk-across suffice.

Families get decent value from watching the bascules raise, though younger kids might find the exhibition rooms a touch dry. History enthusiasts will appreciate the Victorian engineering details. Allow an hour if you're doing the paid tour, twenty minutes if you're just crossing.

Staying at Lovat Parks nearby gives you easy access to this and the Tower of London just across the way, making it a solid central London base without the hotel prices. Early mornings beat the coach tours hands down.
