Families and science buffs visiting Athens will want to stop by this museum dedicated to the preservation and presentation of the natural sciences and Greece’s unique habitats and wildlife. Founded by philanthropists Angelos and Niki Goulandris in 1965 and set in an elegant neo-classical building, the museum focuses particularly on endangered species, environmental issues, and ongoing scientific research. The botanic collection has more than 200,000 species documented, the Gaia Centre offers interactive displays demonstrating the evolution of the planet over billions of years, and life-size replicas of a number of animals and dinosaurs are a perennial favorite.
