Dewees House Marker

Philadelphia, PA

This marker recalls two grand Philadelphia buildings that once stood on this ground before fire swept them away. The Harrison Stratton Mansion belonged to the era when the city's prosperous families raised stately residences reflecting the wealth of a booming industrial metropolis, while the Sunderland was one of the early apartment buildings that reshaped how urban Americans lived as cities densified around the turn of the twentieth century. Their loss to fire was a common fate in an age when timber framing, coal heat, and open flame made conflagration a constant threat to city blocks.

This towering steel barrel once formed the center gun of Turret 1 aboard the USS New Jersey, an Iowa-class battleship that stands today as a museum ship on the Camden waterfront across from Philadelphia. Each of these 16-inch guns could hurl a shell weighing as much as a small car more than 20 miles, and this one spoke in two very different wars — bombarding enemy positions in the Pacific during World War II, then again off the Korean coast a decade later. A single artifact like this collapses the distance between the factory floor of American industrial power and the far shores where that power was felt.

Robert "Bob" Rodale (1930–1990) turned his family's Pennsylvania publishing house, Rodale Inc., into a national voice for organic gardening, preventive health, and physical fitness through magazines like Prevention and Organic Gardening. A committed advocate of cycling, active living, and what he championed as "regenerative" agriculture, he worked from the Lehigh Valley for decades until his death in 1990. Set in the countryside near his Emmaus base of operations, this park carries both his name and his belief that shared public spaces renew the bonds of a community.

In the rolling limestone country of the Lehigh Valley, a new American building material was born. In 1871 David O. Saylor began producing portland cement at Coplay, and by November 1889 the region pioneered the commercial use of the rotary kiln — a continuous-process furnace that turned cement-making from a slow batch craft into true industrial mass production. The valley's rich cement rock and rail links let the industry take root and dominate, supplying the mortar and concrete of a rapidly modernizing nation.
