Coat of arms of Rotterdam

To the surrender of Rotterdam, the weapon was given by William I, Count of Holland and Hainaut in thanks for the support of the lords of the Court of Wena in its fight against Flanders in 1304. The lions are the two red Dutch lions and two black Hainaut lions.

After World War II the motto Sterker door strijd (Stronger through effort) was added to the coat arms of Rotterdam. This motto was granted in January 1948 by Queen Wilhelmina.

Heraldic elements

Escutcheon

In the coat of arms of Rotterdam, the field of the escutcheon (heraldic shield) is green. The field is charged with a white pale. The field and the pale result in three vertical bands in the colours green, white, and green.

Golden lions

The supporters of the escutcheon are two rampant golden lions. The compartment the lions stand on is a stone pedestal. The lions were added to the coat of arms in the 16th century.

Motto

The Queen of the Netherlands wanted to remember the role of the citizens of Rotterdam during World War II and created a motto consisting of the Dutch words "Sterker door strijd", meaning "Stronger through effort". The American town of Rotterdam, New York also uses this motto. In January 1948, Wilhelmina presented the motto as part of the coat of arms of Rotterdam to the city government.

...as a reminder also for posterity of the courage and strength with which the people of Rotterdam bore all the trials of the war and the important part they took in the liberation of the fatherland....—Wilhelmina of the Netherlands

In the coat of arms of Rotterdam, the motto is written on a scroll. This scroll is positioned on top of the compartment under the escutcheon.
