The Natural History Museum located in London, England displays various life and earth-science specimens from different periods of history. There are about 80 million items in the museum and five main collections that exhibit plants, insects, minerals, fossils and animals. The museum contains many specimens collected by Charles Darwin and is widely known for its dinosaur skeletons and skeleton of a blue whale that hangs from the ceiling. The ornate terracotta building is extensively detailed and is typical of high Victorian architecture. The museum has been called “a cathedral of nature” due to its high-arched ceiling and terracotta mouldings that are meant to represent the past and present diversity of nature.
