At the turn of the 20th Century, Pocopson was home to one of the region’s popular recreation spots—Lenape Park, on the Brandywine. Reports differ on its early history. As early as 1858, according to one source, picnics were held on the site, even though the ground was overrun with bushes and vines. The more organized site started in 1877, in the middle of a hickory grove on Sager’s Island, when a group of local residents got together with hatchets and saws and constructed an open-air dance platform.
