Ciência Viva is a dynamic network that integrates 22 science communication spaces and continues to expand. Each Centro Ciência Viva (Science Center) feeds its own local and regional network, connected to municipalities, companies, schools, universities, polytechnics, and research units in its region. There are many excellent science museums worldwide, but none like Ciência Viva's network. One reason for its originality lies in the spaces it occupies. In some cases, spaces were built from scratch, while in others, old buildings with strong local roots were recovered, such as a convent in Estremoz, a church in Tavira, a factory in Aveiro, and even a prison in Vila do Conde. Discovering the science being done today and projected into the future in a place full of memories of the past is a unique experience. Since 1998, more than 13 million people have visited the National Network of Ciência Viva Centers.
