Seven different designs for a flag were proposed during the era of the "pre-autonomous" region. The selected design was that of Manchego heraldist Ramón José Maldonado. This was made official in Article 5 of the Statute of Autonomy:
One. The flag of the region consists of a rectangle divided vertically into two equal squares: the first, together with the mast, crimson red with a castle of Or masoned in sable and port and windows of azure; the second, white.
Two. The flag of the region will fly at regional, provincial, or municipal public buildings, and will appear next to the Spanish flag, which will be displayed in the preeminent place; historic territories [provinces] may also be represented.
Coat of arms
The coat of arms of Castilla–La Mancha is based on the flag of the region, and not vice versa, as is more typical in heraldry. Article 1 of the law 1/1983 describes it as follows:
The coat of arms of the Communities of Castilla–La Mancha is party per pale. On the dexter [the statute literally says "On the first quarter"], on a field gules a castle Or, embattled, port and windows of azure and masoned sable. On the sinister [the statute literally says "The second quarter"], a field argent. On the crest, a royal crown enclosed, which is a circle of Or crimped with precious gems, composed of eight finials, of Acanthus mollis, five visible, topped by pearls and whose leaves emerge from diadems, which converge in a globe of azure or blue, with a semimeridian and the equator Or topped by a cross Or. The crown lined with gules or red.
Some institutions of the region have adopted this coat of arms as part of their own emblem, among these the Cortes of Castilla–La Mancha, the Consultative Council and the University of Castilla–La Mancha.
Most mass-produced flags are commonly 150x90cm / 5x3' or 90x60cm / 3x2', which will often vary from the official size ratio. We now offer a custom-manufactured official size option for our many of our flags.
