Blazon: Argent a cross of Calatrava gules between two keys in base pilewise sable
The arms of the town probably derive from its role as the residence of the clavero of the Order of Calatrava. This role was responsible for keeping the keys of the Order’s stronghold in the castle of Calatrava la Nueva.
There are a lot of things I really like about these arms, starting with the simple but striking design. Points for symmetry, sticking to the law of tincture, using a unique positioning of the keys, and minimal use of color. Extra points for having the charges tie into the area’s history; it’s much more subtle than canting arms, which (to me at least) makes it more interesting. And finally, extra bonus points for teaching me something neat about the structure of the Order of Calatrava.
Blazon: Azure three bees volant or, on a point in chief gules a poleaxe in pale surmounted by two keys in saltire argent
The addition of the point in chief came with Carlo Barberini’s appointment to the position of Gonfalonier of the Church (likely around 1623, when Pope Urban VIII was elected). This position gave the bearer the right to use the papal keys and the umbraculum on his personal coat of arms. It is possible that the poleaxe in this depiction ought to be an umbraculum.
Oh, Barberinis. You can fudge the blazon enough to pretend they’re really bees, and you can add all the Papal regalia you want, but your coat of arms still very possibly started out as horseflies. Personally, I’m never going to forget.
