With colorful costumes and ancient masks, spectators and participants alike gather in the streets of Salsas, Portugal to celebrate the annual winter masquerade. Many of these masquerades are of ancient origin and can often be traced to pre-Christian Celtic and often pre-Roman traditions around the renewal of fertility and life and the end of winter.
