St. Martin’s Day–Martinmas, if you want the older English name–falls every year on November 11th, and it’s one of those holidays that barely registers in the U.S. but is a genuinely big deal across Germany, Austria, and the Low Countries. It’s nominally a Catholic feast day honoring a 4th-century Roman soldier turned bishop, Martin of Tours, but what it actually looks like on the ground is quite different. Children walk through darkened streets after dinner, carrying paper lanterns they made themselves, singing songs, often trailing a man on horseback dressed as Martin in a red cloak. There’s usually a roast goose involved somewhere too.
