|Santa Claus, based on St Nicholas, is a fairly recent addition to the Christmas celebrations. We first hear of him in the poem "A visit from St Nicholas" which dates back to 1823. He is different from Father Christmas, who traditionally wore green and was seen as the herald of springtime. Santa's Grotto, a cavern or magical space in a shop where children could meet Santa, first appeared in Lewis's Bon Marche Department Store in Liverpool in 1879 and was called Christmas Fairyland. The grotto still appears every year, and is now more than 10,000 square feet. The tradition has spread around the world and thousands of department stores and shopping centres now have a Santa's Grotto each year often with model creatures and actors dressed as elves.
