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 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.

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.

Additionally, it supports local tourism and wildlife habitats and exemplifies a completely transformational engineering achievement.
