Abstract
The Neolithic menhir El Gustal is located on a karstificated Coniacian limestone. The original morphology of the monolith and the pit has been preserved, and fragments of limestone filled the hollow. This has made it possible to identify construction phases of the most elementary stone constructive typology. Firstly, the original position of the monolith in the quarry of origin has been determined. Secondly, according to the basic laws of the lever, the forces required to erect the monolith provided by three movements employing two class I and one class II levers have been determined. Thirdly, the fall and subsequent breakage of the menhir due to the shallowness of the pit has been deduced.
