Equipped with a high-resolution astronomical projector, the city's planetarium takes visitors on a journey to the stars. Several programmes, which are suitable for children and adults alike, are hosted by scientifically trained staff who are both enthusiastic and highly detailed in their explanations, helping you to unravel the mysteries of the skies. Also on display is an astronomical clock built between 1930 and 1952 by Reims-born Jean Legros from pieces of Meccano.
