Sassi Ritti four aniconic menhirs
The Sassi Ritti site (a short distance from San Piero) hosts a series of four aniconic menhirs present since immemorial, from which the toponym derives. The menhirs of Elba on the slopes of Perone Mountain could have a ritual function, similarly to what happens in the megalithic sites of southern Sardinia (Pranu mutteddu) and in the south of Corsica (Caurìa and Palaggiu), where these alignments of menhir are called filarate. Characteristics that are always observable is the exact North-South direction of the menhirs; this arrangement could refer to a precise desire to allow the rays to constantly illuminate the longer sides of the monoliths throughout the day. The dating can be traced back to a period between the 3rd and 2nd millennium BC
