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 oldest menhirs (standing stones) were erected in Portugal between 5000 and 4000 BC. The age of this menhir is unclear.

What's particularly interesting about the Xerez stone group is its square shape. The menhir is located in the center, surrounded by smaller stones. A concrete path leads from the Orada Monastery to it—is this really necessary? A regular path would certainly have sufficed. The entire area appears very neglected.

The Xerez Cromlech stands on open land, close to the Convent of Orada, and with a view of the walls of Monsaraz. It is the second "home" to prevent it from being submerged by the Alqueva dam. The 55 granite menhirs of the Xerez Cromlech have already been to other places because they were moved here, to the vicinity of the village of Telheiro, in 2004, to prevent submersion by the Alqueva dam. The cromlech was in front of Monte Xerez, close to a dolmen, about 5km from Monsaraz.

Giraldo Castle, or Geraldo Castle, is located in Nossa Senhora de Guadalupe, in the current parish of Nossa Senhora da Tourega and Nossa Senhora de Guadalupe, in the Municipality of Évora, District of Évora, in Portugal. It is a castro, a proto-historic fortified structure with origins in the Bronze Age or even the Chalcolithic, but with traces of later occupations. It has a subcircular plan and an outer perimeter of 114 meters. The wall that has survived to the present day probably belonged to a period of medieval occupation. Sources from the 15th century refer to the fortification, associating it with the presence of Geraldo Sem Pavor, a warrior who conquered Évora from the Muslims in 1165. It is currently in the process of being classified.

The best time to visit Évora's natural monuments is generally during the spring (March to May) and autumn (September to November). During these seasons, the weather is milder and more pleasant for exploring the outdoor sites. Summers can be very hot, while winters can be cooler and wetter, potentially impacting comfort during extended outdoor visits.

The Great Dolmen of Zambujeiro is another impressive, though perhaps less frequented, archaeological site that offers a profound historical experience.
When visiting the natural monuments, especially if you plan to hike, it's advisable to bring comfortable walking shoes, water, sun protection (hat, sunscreen), and appropriate clothing for the weather.

Their preservation highlights both archaeological importance and the enduring natural setting.
