What stands out about Gettysburg’s past
Read from the archive, the National Register and the record. The page puts what stands out first.
Gettysburg was founded by natives of Adams County, Pennsylvania, in the late 1820s. When the settlement was platted by John Hershey in 1842, the community was named for Gettysburg, the county seat of Adams County. The community's first church was a congregation of the Presbyterian Church in the United States of America, established in 1847 or 1848, while the first school was built in 1850.
By the 1860s the village had an active business sector including general stores, shoe shops, cabinet makers, wagon/carriage shops, harness shops, tanning yards, cooperages, blacksmiths, tinning shop, tailors, physicians, a hotel, grain elevator, flouring and saw mills. Several saloons opened but soon failed.
