Based in a renovated, over 100-year-old power plant building just opposite Old Town and the first of its kind in the Baltics, the Energy Discovery Centre is the place to discover science with a hands-on approach. The centre has unique historic devices and more than 100 hands-on exhibits dealing with themes such as electricity, magnetics, nuclear energy, sound and optics. Perhaps one of the coolest exhibits will actually allow the visitor to experience 'lighting' - up close and personal, via the Tesla Coil. They also have a full-dome planetarium, temporary exhibitions, interesting science theatre programmes and workshops (theatre and workshops are available for groups, pre-booking is necessary).
