December 4 th - St. Barbara's Day (Barbórka).
One of the most celebrated days in Upper Silesia, where Gliwice is located.
St. Barbara is a patron of coal miners.
Here you are the miners' brass orchestra before a concert. Miners are dressed in the special uniforms consisting of black suit and hat with a feather. The color of the feather depends on the rank of the miner. As you see, the red colour is reserved for musicians :)
