They are escorted by ‘Joaldunak', a group of hefty bellrings clothed in sheepskins worn over lace petticoats and tall pointy hats bedecked with colourful ribbons who stomp through the town swinging horsetails and with giant cowbells strapped to their backs.
The ritual, held for three days at the end of January each year, has something do with old agricultural traditions of shepherding and is designed to ward off evil spirits and keep the stock safe for the year ahead.
The pagan festival, which dates back hundreds of years was banned during the Franco dictatorship but has seen a resurgence in popularity in recent years, though no one now can remember how or why it began.

We have no idea what's going on here either, but it looks like fun!
