The original waxwork attraction, founded by the Swiss sculptor Marie Tussaud in the early 19th century, now sprawls across multiple floors of Marylebone Road. The figures — politicians, royals, celebrities, sports stars, musicians — range from uncannily accurate to mildly unsettling.
It's expensive, often crowded, and pitched squarely at tourists rather than Londoners. Children tend to enjoy it; adults' mileage varies considerably. Book online well in advance to get a significantly lower price than the walk-up rate.
