The Postal Museum

The Postal Museum tells Britain's 500-year postal story through everything from medieval letter delivery to modern parcel sorting, but the real draw is Mail Rail - a 15-minute ride through the actual underground railway that carried London's mail from 1927 to 2003. You'll sit in purpose-built carriages that glide through narrow Victorian tunnels, past original platforms and sorting stations frozen exactly as postal workers left them. The museum upstairs covers Penny Black stamps, wartime postal services, and those red postboxes you see everywhere - it's surprisingly engaging even if you've never thought twice about how your letters get delivered.

The Mail Rail experience feels like stepping into a secret London most people never knew existed. The tunnels are genuinely atmospheric - dimly lit brick archways with authentic railway signals and abandoned mail bags still scattered about. Upstairs, the museum flows chronologically through British postal history with interactive sorting games, vintage uniforms, and a recreation of a 1930s post office counter. The whole place has that satisfying blend of nostalgia and clever engineering that makes you appreciate something you'd normally take for granted.

Most visitors rush straight to Mail Rail and barely glance at the museum proper, which is a mistake - the upstairs exhibits are genuinely well done and provide context that makes the underground ride more meaningful. Adult tickets cost £17, which feels steep for what's essentially a 15-minute train ride plus a small museum, but the novelty factor justifies it if you're curious about London's infrastructure. Skip the gift shop unless you're genuinely into postal memorabilia - it's overpriced tourist tat.
