Vexillological description
It is a rectangular field —the cloth of the flag —with a 2:3 ratio, cut into eight gironnies that alternate red and black, with the coat of arms of the city in the centre.
- Field
- eight gironnies (triangular wedges that come out of the centre), four red and four black.
- Coat of arms
- gold, with the head of a bull, two black eagles, a red castle and three small shields; it is topped by the crown of five towers of a city.
- Stripes
- there are none; a stripe is a band of colour, and here the colours only change in the gironnies.
