One of the most beloved folklore stories from Cologne dates back to the Middle Ages and tells the story of the Heinzelmännchen, the house gnomes. These mythical creatures were said to do all the work of the people of Cologne during the night, so when the citizens woke up in the morning, all their work was done. The Heinzelmännchen were tailors, shoemakers, bakers, and would perform any other task necessary. However, they would only work in secret and expected nothing in return but to be left undisturbed. Each household would leave out a small pitcher of cream as a token of gratitude. However, they would never be seen as they refused to labor if they were being watched. This harmonious arrangement continued until a tailor’s wife, driven by curiosity, scattered peas on the floor to make the gnomes slip and reveal themselves. It worked, but it angered the Heinzelmännchen who promptly vanished, never to work again. Thus, the people of Cologne have had to do their own chores ever since.Today, the tale of the Heinzelmännchen is deeply ingrained in the local culture and is celebrated during the Christmas season. A large number of statues and monuments dedicated to the Heinzelmännchen can be found all around Cologne, including the famous fountain at the city center. This tale serves as a cautionary note about the dangers of letting curiosity disrupt harmony and peace.
