Natural History Museum

With some 80,000,000 specimens (not all on display!) spanning more than 300 years of collection, it is absolutely worth the visit. Like so many galleries and museums of London, visitors can enjoy complimentary entry. Although we'd suggest leaving large bags in the hotel room. The building has been a celebrated epicenter of learning for centuries, with detailed displays inside and eye-catching features on the building's exterior. There is a collection of many dozen terracotta animals acting as gargoyles all around the building.
