Saint Nicholas (Saint NICOLAS), bishop of Myra, to whom the church in Castelnau-Barbarens is dedicated, is – along with Saint Martin – one of the most popular saints of all. Almost every child in Germany - and far beyond - should know his commemoration day, December 6th. On the eve of this day, the children used to put their shoes or boots in front of the door – which of course had to be cleaned with great care – so that they could be filled with gifts by St. Nicholas during the night. In more agricultural areas, it was also customary for the children to provide a small amount of food for the donkey, St Nicholas' riding animal (according to another tradition, it was a white horse).
