Immersed in the pine forest of the "Litorale Pisano" and in the coast of Ligurian Sea (even if the name of the village refers to Tyrrhenian Sea, in Italian Mar Tirreno), Tirrenia is in the northern side of the coast of Tuscany and next to the Parco Naturale Migliarino, San Rossore, Massaciuccoli, between Pisa and Livorno.

In the 1930s, places for studying film were constructed, and la Pisorno was built to expand the ideal of fascism in Italy and to make propaganda.

Today, in the area of Tirrenia near Livorno, the old colonies built by Mussolini for orphans are being restored since they were abandoned after World War II.

For many years, retired American personnel who had remained in Italy due to having married Italian women, provided night security.

Fourth of July celebrations were often held on the beach, as it was fairly easy to set up pyrotechnical displays without fear of causing fires.

Tirrenia is especially visited by young people, mostly from Pisa and Livorno, because of the vast quantity of pubs and discos that the village offers.

With the presence of a training center of the Italian National Olympic Committee (CONI), many athletes go to Tirrenia to practise and at times relax by the seashore.
