Wax museums might not be the most popular in the modern age, but Madame Tussauds has enough history in the bank to regain more than enough credibility to justify a visit. The whole thing started as an 18th century travelling show, before blossoming into the most famous collection of wax figures on the planet. If you want a selfie with anyone from David Beckham to Mahatma Gandhi, The Incredible Hulk to Miley Cyrus, this is the (somewhat pricey) place to go.
