The 4th of December is a special day for Polish miners - it’s Barbórka (pronounce: Barboorkah) - name's day of their patron, St. Barbara.
Polish miners are probably one of the few professions that still strongly cultivate traditions. Today they don’t go underground to work. Instead they organise marches and huge celebrations called beer halls .
On Barbórka and other important days, like weddings, funerals, etc. miners wear a special uniforms consisting of a black suit, a hat with a plume and a small sword. The colour of plum depends on rank: black is for miners, white - mining engineers, green - chief director, red - member of orchestra, red and white for orchestra conductor.
