According to legend, April 30 is the night when witches would flock to the highest peak in the Harz mountains to celebrate the arrival of spring and the fading winter. Similar to Halloween in the U.S., Witches Night (Hexenacht or Walpurgisnacht) is a night full of revelry and good-natured mayhem. Many celebrations, though maybe not this year, include local residents dressed as witches dancing around a large bonfire with loud music to fend off the evil spirits and welcome the new season.

Don’t be surprised if you wake up the next morning to find your trashcans flipped over or a few plants missing. Teens and children are notorious for playing pranks on unsuspecting neighbors, especially those who may be new arrivals to Germany. Secure your favorite lawn gnomes or flamingos, and put away anything you don’t want taken or damaged. Otherwise, it may be considered fair game to local pranksters. Although these shenanigans are meant to be in good fun, there is always the chance for vandalism. Just keep a watchful eye out.
