The Copernicus Science Centre is the largest science museum in Warsaw, Poland and houses over 450 interactive exhibits! In 2015 alone, it recorded over 5 million visitors since its opening that year. The entire complex comprises a two-storey building of exhibits, laboratories and conference centres, a workshop and garage, a planetarium as well as a Discovery Park. Several of its permanent attractions include 'Humans and the Environment', 'Roots of Civilisation' and 'RE: generation', a gallery made specially for young adults. Apart from its permanent exhibits, the centre also houses roving ones like 'Experiment!', its very first exhibit which saw more than 10,000 visitors in a day. Ever since 2006, it has been traveling around large cities and smaller towns to give residents a first-hand experience with scientific experiments.
