The coat of arms of Lower Silesia, and simultaneously of Silesia, shows a black eagle with silver crescent with cross in the middle on its chest (the emblem of Silesian Duke Henry the Bearded, Polish: Zgorzelec) on a golden background. It has been assumed in the tradition that the coat of arms and colors of Lower Silesia are simultaneously used as symbols of Silesia as a whole.^[1]

The coat of arms of Upper Silesia shows a golden eagle on a blue background.^[1]

In the Polish heraldry, the Silesian eagle is usually not crowned (with the exception of Cieszyn Silesia), in the Czech and German it is usually the opposite.
