Simmetria has been planning and organizing guided tours of Italian cities and archaeological sites for 25 years with a very different spirit than usual. The same spirit is pursued by the Symmetry Institute. It does not favor "tourist" use but is aimed at those who want to find the origins, purposes and rhythms of the remains of the "Ancients." To book a guided tour, you must call or send an email at least 10 days before the event. Generally groups are organized ranging from a minimum of 10 to a maximum of 25 people. The places proposed are announced in the Foundation's periodic newsletters and participation has fixed costs that vary from year to year and do not include the entrance ticket. sites managed by the state or by public or private entities. The museum and the library constitute a real didactic path in which texts and works exchange information. Visiting the Symmetry Institute can be extremely informative at any level of education.
