The Musée d'histoire naturelle - Guimet houses collections of natural science, anthropology, and Earth Sciences, which are complemented by exhibitions showcasing arts and crafts. The museum boasts four major exhibitions named "Origins - Stories of the World," "Species - the Web of life," "Societies - Human theatre," and "Eternities - Visions of the beyond." The first exhibition delves into questions of origin, covering the Big Bang theory, the history of the universe, the emergence of life, and the evolution of humans. The second exhibition, "Species," explores the relationships between humans and animals and the evolution of different species. The third exhibition, "Societies," focuses on human societies and their building of communities, while "Eternities" tackles the meaning of life, the inevitability of human death, and how different societies have approached this question.
The museum's dimensions are impressive, with a height of 44 m (144 ft), a length of 150 m (492 ft), and a width of 83 m (272 ft). Its total area covers 22,000 m2 (238,000 sq ft), of which 6,500 m2 (70,000 sq ft) is devoted to exhibitions, three times the size of the previous museum's exhibition space. The museum offers nine concurrent exhibitions, four permanent and five temporary, along with four discovery spaces and two auditoriums. Although the construction budget was initially set at €153 million, the controversial final cost is now predicted to reach nearly €300 million.
