Torre d'en Galmés is the largest prehistoric site on Menorca, set on a hilltop between Alaior and Son Bou with panoramic views of the sea. The settlement includes three talayots (stone watchtowers), a taula precinct (a T-shaped megalith surrounded by carved stone benches — thought to be a sacred enclosure), hypogea (underground burial chambers), and the remains of many domestic buildings. The entire ensemble is spread over several acres of scrubby hillside.
The site has been excavated over decades and is well presented, with explanatory panels and paths between the main monuments. It gives a better sense of what a working Talayotic community looked like than the smaller standalone monuments scattered around the island. The Son Bou beach is visible from the hilltop — the combination of prehistoric ruins and a view of the sea is typically Menorcan. Allow an hour or two.
