"Once an encampment for Union troops during the Civil War, 12-acre Meridian Hill Park is now a central gathering space for friends and fitness enthusiasts. Running groups, yoga classes, and personal training sessions all meet at this urban hilltop park, no matter the season. Stroll around the perimeter to admire the 13-basin, Italian-style cascading fountain—the longest in North America—as well as statues commemorating figures such as Joan of Arc. In fair weather, join the hundreds who flock here over the weekends for picnics, impromptu sporting matches, and dog walking (and watching), as well as the Sunday drum circle whose rhythms have been sounding into the night since the 1950s."
