A conjuratory or exconjuratory (Aragonese: esconchurador, Catalan: comunidor, Spanish: conjuratorio) is a small religious building from which ceremonies were conducted to bless the fields and ward off calamities caused by the weather, like storms, hail and excessive rain that could ruin the harvests. Usually these buildings are attached to a church building or a hermitage. Exconjuratories were common in the ancient villages of the Pre-Pyrenees and the Pyrenees, especially in Aragon.
