The Academy of Science of Siena, known as Accademia dei Fisiocritici, is one of the oldest scientific institutions in Italy. In the eighteenth century it had enormous prestige in cultural circles all over Europe, and major intellectuals of the time among its members. Founded for the purpose of studying the truth of natural phenomena, more than three centuries later it continues its mission of scientific communication through museum teaching, publication of journals, and activities and events open to the public. Today the Accademia is a true cultural space, hosting and organising concerts, theatre, art exhibitions, children’s animation and many other initiatives.
