A pass for a family (up to 2 adults and 2 children) at the EcoTarium Museum of Science & Nature in Worcester MA. EcoTarium is well rooted in the Worcester community as an organization dedicated to the study of science and nature. The private, non-profit institution was founded in 1825 as the Worcester Lyceum of Natural History and was incorporated in 1884 as the Worcester Natural History Society — EcoTarium's legal identity. Our transition from the New England Science Center to the EcoTarium in 1998 refocused the museum on its roots in the natural sciences with a focus on hands-on exploration and discovery. The name change accompanied a major capital development program that has transformed the building and grounds into an accessible learning and discovery center for families.
