European Settlers James Patton, who came to America at age 17 and moved to
North Carolina in 1793, started the settlement of Canogege (spelled "Conegoge" by George P. Donahoo). Patton said in an 1839 letter to his descendants that the place was "settled by a moral and orderly people." Greencastle was founded in 1783 by John Allison from the Barkdoll House. The town was named after
Greencastle, County Antrim,
Northern Ireland. It was originally composed of 246 lots. By 1790 there were about 60 houses in Greencastle, homes to approximately 400 people. The town of Greencastle had grown by the mid-nineteenth century to 1,125 residents.
Latter Day Saint settlement In 1845, following the
succession crisis in the
Latter Day Saint movement,
Sidney Rigdon (one of the three main contenders along with
James Strang and
Brigham Young for leadership of the Latter Day Saints following the
death of Joseph Smith) took his followers to Pennsylvania and formed a
Rigdonite Mormon settlement at Greencastle. This settlement had approximately 200 followers. They founded the New Jerusalem settlement between Greencastle and
Mercersburg, published the
Conochoheague Herald newspaper in Greencastle, and made plans for the construction of a temple. The Rigdonite Mormon settlement at Greencastle only lasted a few years; some former Rigdon followers went to
Utah to join Brigham Young, while
William Bickerton, who had opposed Rigdon's move to Greencastle, would eventually reorganize the remaining Pennsylvania branch of the Latter Day Saint movement in
Pittsburgh as
the Church of Jesus Christ (Bickertonite).
Civil War Early in the
Civil War, Greencastle and neighboring
Franklin County communities raised the
126th Pennsylvania Infantry. In the summer of 1863, the war touched close to home when
Confederate General
Robert E. Lee and his
Army of Northern Virginia invaded southern Pennsylvania during the
Gettysburg campaign. From mid-June to early July, those residents of Greencastle who had not fled to safety lived under Confederate rule. On July 2, concurrent with the
Battle of Gettysburg in neighboring
Adams County,
Captain Ulric Dahlgren's Federal cavalry patrol galloped into Greencastle's town square, where they surprised and captured several Confederate
cavalrymen carrying vital correspondence from
Richmond. After the Battle of Gettysburg, Lee's army began its retreat to
Virginia on July 4 and 5. He sent
John D. Imboden's cavalry to escort a large wagon train carrying Confederate wounded. The train, nearly in length, wound its way through the streets of Greencastle, where a few men of the town attacked the wagon train with axes and hatchets. They succeeded in disabling several wagons before Confederate cavalry chased them away.
Modern era Following the war, Greencastle grew considerably in the late 19th century during the
Industrial Revolution, having several industrial factories built inside the town limits, including the Crowell Manufacturing Company, which constructed farming equipment. In 1902, Greencastle businessman Philip Baer began a tradition where the town holds a triennial social event known as "
Old Home Week". Every three years, Greencastle townspeople and former residents come together for one week in August in a town-wide reunion to reminisce and fellowship. Baer performed prolifically in a
minstrel show which included the use of
blackface. As recently as 2013, the program has featured a "modern minstrel." The most recent Old Home Week Celebration occurred in 2022; the next one will be in 2025. The
Greencastle Historic District,
Mitchell-Shook House, and
Martin's Mill Bridge are listed on the
National Register of Historic Places. Greencastle contains many Christian church congregations with longstanding heritage and rich history. The present-day
Methodist church has origins dating back to 1805 when
Christian Newcomer conducted services in the area. ==Geography==
