Celebrate Maryland Day all weekend, at the Smithsonian Environmental Research Center! Experience history through the eyes of enslaved and free Marylanders at the 1735 Woodlawn History Center, the oldest building in the Smithsonian still in its original spot. Walk through the first-floor exhibits on your own, or join a free guided tour on Saturday at 3pm, which includes the upstairs (signup required). Our four nature trails will be open for hiking from 8am-4:30pm, where you can explore forests, marshes and shorelines. Don't forget to bring a picnic lunch to enjoy beside the water.
