Rêgo Grande I, in Calçoene, preserves a monumental landscape built by Indigenous peoples before European colonisation. Large granite blocks are associated with funerary contexts. Archaeological research has recovered urns and pottery fragments, showing that the stones belonged to wider social and ritual practices.
IEPA’s work in the Calçoene river basin since the 2000s has expanded knowledge of this heritage. Studies of burial pits also examine ceramic decoration and the knowledge involved in making the vessels. Possible astronomical connections should be presented as research interpretations, without reducing the site’s history to a comparison with Stonehenge.
During a visit, consider the arrangement of stones and their relationship with the landscape. Confirm access and guided-visit conditions with the management. Do not climb megaliths, move fragments or remove anything: the position of material is itself archaeological evidence.
