Flag of Aveiro

How it came about

Aveiro is a city in central Portugal. Its flag was published in 1960, on 9 August, following the 1930 municipal model.

The coat of arms of the city bears a white eagle on a green ground, with a sun and a moon. On the flag, the green stays inside the coat of arms: the field uses only red and white.

Fun facts

1. A gyronny of eight points

   The technical name of the drawing is “gyronny”: eight wedges that all come out of the centre and alternate two colours. It is a motif of heraldic origin, but here it works as a geometric ground for the coat of arms.

2. The green does not leave the coat of arms

   The coat of arms of Aveiro has a green ground, but the field uses only red and white. The green stays enclosed inside the shield. It is a decision that makes the flag have two colours and the coat of arms three.

3. Sun and moon in the coat of arms

   The coat of arms of the city bears a white eagle on a green ground, with a sun and a moon. It is a solar and lunar coat of arms, one of those in which the eagle looks towards both stars.
