Vexillological description
It is a rectangular field divided diagonally: white takes up the upper half and purple the lower one. In the centre, over the two halves, is the coat of arms of the town with its crown. I did not find any rule describing the flag, so this is what the image shows.
- Division
- a diagonal line running down from near the upper corner of the flagpole to the lower corner of the fly side.
- Coat of arms
- that of Ateca, centred; around it are written the words «Muy Ilustre Villa de Ateca».
- Colours
- white and purple, with no stripes or border.
