London is one of the best market cities in the world, but most visitors only hear about the same few names. This guide maps around 20 interesting London markets that are worth exploring if you want to see a more local, varied and surprising side of the city. Some are good for food. Some are better for vintage finds, books, antiques, flowers, independent makers, second-hand treasures or simply people-watching. A few are well known, but included because they still have a strong identity. Others are the kind of places you may never find unless someone points you there. This is not a luxury shopping guide. It is a practical London Advanced map for people who like wandering, discovering neighbourhoods, browsing slowly and seeing the city through its streets, stalls and local communities. Use it to plan a weekend route, add a market stop to a wider London walk, or build your own day around food, vintage, photography, local life and unexpected corners of the city.
