The Mummers Museum is dedicated to the Philadelphia New Year's Day tradition known as the Mummers Parade. The roots of the tradition date back centuries, but the first official parade occurred on New Year’s Day 1901 and continues annually. The museum, which opened in 1976, houses a rich collection of Mummers' paraphernalia and memorabilia, including spectacular costumes, a few of which date to the turn of the 20th Century.
