The Mari Lwyd

31 December & 3 January (6pm - 7pm)

Join us for a warming drink, music, and a mischievous Mari in this fun Welsh tradition. When Mari and her group get to Newton House, they will sing Welsh language songs or wassails, and indulge in a ritual called pwnco: an exchange of rude rhymes with the person who lives there. If the Mari and her gang get entry, the household is said to have good luck for the year. The Mari is well-known to be mischievous – trying to steal things and the chase people she likes – as she goes about her bidding.  Wear suitable shoes and cosy clothes.
