The date of construction is unknown but the proximity of this temple to the Residence of the Counts, as well as the fact that the title of Count was granted on the Name Day of Saint Anthony, June 13th, suggest the possibility that this chapel was built at the end of the sixteenth century and beginning of the eighteenth century, by the Counts of Alcoutim as a private temple. The patron saint, Saint Anthony, suggests that this edification is associated to fishing in the Guadiana.
The interior holds an altar in masonry and a niche tiled in red adobe with the statue of Saint Anthony. Notice the tiled barrel vaulting and the highly accomplished lintel over the portal.
In 2008 it welcomed the renovated Museological Exhibition of Sacred Art.
