The Chapel of the Holy Christ of Antigua is located adjoining the west angle of the Fatetar Castle which stands on the summit of a hill north of the Espera town, with which it forms and architectural unit. The Chapel of the Holy Christ of Antigua served as a church to the inhabitants of the town until the consecration in the early seventeenth century, the Church of Our Lady of Grace, with the patronage of St. James, patron of the Christian Reconquests, wich suggests its pssible construction by the first Spanish forces that garrisoned the castle from the second half of the thirteenth century.
