Join the Harvard Museums of Science & Culture on the longest day of the year—free of charge—to explore the galleries and new exhibitions at the Harvard Museum of Natural History, the Peabody Museum of Archaeology & Ethnology, the Collection of Historical Scientific Instruments and the Harvard Museum of the Ancient Near East.

Step outdoors to enjoy lively musical and circus performances, play mini-golf, enter membership and shop raffles, and make a flower crown. Ice cream, mocktails and snacks are available to purchase from food trucks and vendors.

Free event parking is available at the 52 Oxford Street Garage. Please note that Divinity Avenue is closed to traffic during the event. This festival is part of HMSC’s 10-Year Anniversary celebration.
