Alto de São Gens
Highlight • Summit
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.
