The Feast of St. Lucia in Sweden is observed with an essential tradition where young girls dress in white robes with red sashes, symbolizing purity and sacrifice. They wear wreaths adorned with candles on their heads, representing bringing light during winter's darkness. The eldest daughter typically plays St. Lucia, leading a procession that sings traditional songs. Families often celebrate with saffron buns called lussekatter, enjoying the festive treat together. This ritual reflects the cultural significance of light in the midwinter season and strengthens familial and communal bonds through shared customs and celebrations.
