Coat of arms of Bytom

The coat of arms of Bytom was adopted by an 1886 resolution of the town council.

It is composed of two symbols. The left (heraldic: right) half shows a miner digging with a pickaxe for smithsonite. It is based on a 14th-century town (aldermen) seal, referring to the centuries-long tradition as a mining area. The right (heraldic: left) half features a golden eagle on a blue field - the symbol used by the Upper Silesian dukes of the Piast dynasty.
