Son Fornés is an archaeological site from the prehistoric era. It is located in the vicinity of the town of Montuiri, on the island of Mallorca. It dates back around two thousand years. It was built in the Talaiotic period (tenth century B.C.) and was maintained until the middle of the seventh century B.C. . The Talaiotic period was, without a doubt, the period when this prehistoric enclave was most greatly occupied.

It was occupied almost continuously until the first century, and from then on was visited sporadically during the Byzantine and Islamic period. It is partially excavated, especially the main area, and has been well preserved. Finding the site is very easy. It is perfectly visible and can be reached by car, with a 100-metre walk after parking.
