The Roman wall, the medieval plague pit, the oldest pub in London, and the alley where Shakespeare's company performed before the Globe was built. All within a 90-minute walk.

The permanent collection at Tate Modern has rooms that will genuinely change how you think — but most visitors only see the main hall and leave. I take you through the Rothko Chapel room, the Bourgeois spiders, and five works that took my breath away when I first saw them.

Two hours in the National Gallery with an art historian who knows which rooms most visitors skip — the early Flemish masters, the Turner room at the back, and the painting that made Constable weep. No audio guide headphones required.
