The Gentleman, Knight, Baron, and the like, do wear their helments with the beaver looking over the shoulder, to signify, that they, marching before their Duke or Captain (as at the first that dignity was but an office) do regard and look towards him to attend his pleasure and direction in what he will command.
– From The Blazon of Gentrie by Sir John Ferne (1586), p139
Blazon: Azure on a base a triple-towered castle or windowed gules in the dexter; in the sinister a knight armored bearing in the dexter hand a lance proper and in the sinister hand a banner of the third a cross argent mounted on a horse salient of the last saddled, bridled, and caprisoned also proper
The knight is potentially a reference to the Knights Hospitaller, who took control of the town in 1189 – the banner matches their arms. The name of the town is probably derived from the Arabic “Al-kasar,” or “fortified castle.”
Blazon: Sable on a broken bridge argent over water in base barry wavy gules and azure, on the dexter half a passion cross or, on the sinister a knight in armor proper; in chief a molet of five points with rays of the fifth
The black field may be an allusion to the name of the city (negro meaning “black” in Spanish).
