Blazon: Vert a castle on a chief or a cross of Santiago gules between two hemp leaves of the field
The hemp leaves (cáñamos) are a canting reference to the town’s name, which it has borne since 1575.
Blazon: Per pale azure a representation of the local church of Christ of the Valley argent and of the last a cross of Santiago gules, pointé in base or a bunch of grapes slipped and leaved vert
The characteristic church featured on the arms was built in the sixteenth century on the site of the former hermitage of St. Helena, where (according to legend) Christ appeared in the form of a strange traveler.
Blazon: Per pale vert a castle triple-towered or windowed azure and argent a cross of Santiago gules, pointé in base azure from a base proper a column argent
The Order of Santiago took possession of the region around the town in 1186, ultimately using it as a military basis during the Reconquista. They were formally granted ownership in 1243; this is likely the source of the cross of Santiago. I can only speculate that the column is a reference to the many local ruins from Roman times.
In use since at least 1984
Blazon: Per quarterly I sable a cross of Santiago gules, II vert a castle triple-towered argent, windowed sable, III gules a crown or, IV azure two clasped hands, in chief a baton and sword in saltire argent
The base two quarters are both references to the previous arms, which incorporated both the crown of Charles V, Holy Roman Emperor, and the sword and baton as symbols of civil and military authority.
Blazon: Azure a castle triple-towered or, windowed sable, in chief a script M argent, all within a bordure of the last charged with four crosses of Santiago gules
The script M is a common symbol of the Virgin Mary, who is a patron saint of the town under the title Virgin of the Hawthorn.
Blazon: Per pale argent a cross of Santiago gules and azure a castle triple-towered or on a mount in base proper, surmounted in base by a basin argent of water barry wavy of the field and the last; pointé in base or a galero vert, in the fess point an alms bag, in base a croizer and a patriarchal cross in saltire sable
The archbishop’s regalia in base is presumably a reference to St. Thomas of Villanova, who was born in Fuenllana in 1488, and later canonized in 1658.
