Going to the theatre has always been an important part of any trip to London. Not only does the city boast some of the great theatres but ticket prices are usually reasonable. It is also home to the world’s longest-running play, The Mousetrap by Agatha Christie. The story has been at St Martin’s Theatre for over seventy years. London also hosts the world’s two longest-running musicals. Les Miserables and The Phantom of the Opera have been running on the London stage for nearly forty years. Les Mis, as it is commonly known, celebrates its fortieth birthday in October 2025, and Phantom passes the forty-year mark a year later.

London has many street markets that visitors can visit. Smithfield Meat Market and Billingsgate Fish Market are probably the most famous wholesale markets in the capital, but both are facing great challenges. Despite operating for centuries, they face an uncertain future, with supermarkets preferring to deal directly with their suppliers these days.
