At the top of the Serra d’Ossa, at an altitude of 650 metres, stands the Alto de São Gens. Among the ruins of the old chapel dedicated to the saint, memories of an occupation that dates back more than three millennia, to the Bronze and Iron Ages, echo. This archaeological site, shrouded in legend and symbolism, was later associated by the monks of the Congregation of São Paulo with the mythical Mount of Venus, the refuge of Viriato, the legendary Lusitanian leader who, according to tradition, descended from here to confront the Romans.

The Anta da Candeeira, or Anta da Herdade da Candeeira, is one of the many megalithic remains that dot the Alentejo, more precisely in the district of Évora. In the Portuguese lexicon, “anta” refers to the approximately five thousand megalithic monuments (or dolmens) spread across the west of the Iberian Peninsula. These enigmatic stone structures were built during the Neolithic period by communities that inherited the Cardial or Impressa cultures. Silent testimonies of a distant past, they continue to fascinate those who venture into these lands of history and stone.
