London's hidden gems: Underrated landmarks you need to see in the UK capital

Published on 28/07/2026 - 10:23 GMT+2 Beyond the unending queues for the London Eye or selfie stick-filled crowds around places like Oxford Circus or Elizabeth Tower (which houses the Big Ben bell), voters have had their say on London’s most underrated spots that many visitors end up walking straight past. ADVERTISEMENT ADVERTISEMENT The Secret London website asked its followers on Facebook the question: “What’s the most underrated London landmark?” After receiving more than 250 suggestions of attractions, sights and landmarks, the results are in. Postman's Park A quaint green space just a stone’s throw away from the architectural marvel of St Paul’s Cathedral, Postman’s Park topped Secret London’s list. Like many other places across the UK capital that have a charming backstory, the park's moniker comes from its previous lunchtime popularity among postal workers who frequented their breaks there while working at the nearby old General Post Office. Tucked away from the city's hustle and bustle, the park's pathway weaves through the garden from east to west, while benches surround the seasonal bedding display that features as a centre piece to the garden itself. Movie buffs may also recognise the central London park from its role in the 2004 film, “Closer”, which starred Jude Law, Natalie Portman, Julia Roberts and Clive Owen. For Secret London, however, the park is more than just a pretty place. “Postman’s Park is home to a truly heartfelt memorial,” the website said. “Within the site, you’ll find a memorial with plaques dedicated to ‘ordinary’ people who acted heroically. Each one is dedicated to someone who gave their life in an attempt to save someone else.” Where else can travellers go to see London’s hidden gems?
