In parts of Europe on the 5th of December, the Eve of the Feast of St. Nicholas the Saint visits homes to give gifts to good children. He is accompanied by his dark counterpart The Krampus, who teases and punishes naughty boys and girls. Krampus festivals or runs are popular throughout Europe and now in America but had never been held in the UK, until 2015 with the very first Whitby Krampus Run, which was very well received even by naughty children and again in
2016, 2017, and 2018 with considerable media attention.
WKRV 2019 is now in the planning
So be prepared, for Krampus is coming.
Here is a link to a good introduction.
