Silver Spring Presbyterian Church

Silver Spring Township, PA · est. 1947

Among the very first Europeans to push into the Cumberland Valley were Scotch-Irish Presbyterians, who in 1734 gathered a congregation on land held by James Silver. The stone church that still stands was raised in 1783, in the hopeful early years of American independence, and was carefully restored in 1928 to its 18th-century form. Nearly three centuries on, worship continues on the same ground.

George Croghan (c.1718-1782)

Hampden Township, PA · est. 2021

Around 1740 the Irish immigrant George Croghan set up a trading post on this ground and built it into one of the most far-reaching British trade networks in colonial America. Reaching west into the French-contested Ohio Country, he learned Native American languages and customs to secure the furs that Europe craved. For three decades he was among Britain's most important go-betweens at treaty conferences with Indian nations.

Peace Church

Hampden Township, PA · est. 1948

Raised in 1798 by a German Reformed congregation, this plain limestone meetinghouse soon came to be shared: a Lutheran congregation bought a half-interest in 1806, and the two worshipped together here until 1866. Left unaltered for more than two centuries, it survives as a rare example of an early Pennsylvania union church, still used once a year by St. John's Lutheran. Its very name reflects the neighborly compromise that let two faiths share one roof.

Peace Church

Hampden Township, PA · est. 1947

In the Cumberland Valley of the 1790s, a Reformed congregation raised this sturdy meetinghouse in 1798, and by 1806 shared it with a Lutheran congregation — a common arrangement among Pennsylvania's German settlers, who often pooled resources for a single "union church." The two flocks worshiped side by side under one roof until 1866. Left in its original form rather than modernized, the building survives as a rare, unaltered window into early frontier faith.
