Adams County, Pennsylvania

Adams County is a county in the Commonwealth of Pennsylvania. As of the 2020 census, the population was 103,852. Its county seat is Gettysburg. The county was created on January 22, 1800, from part of York County, and was named for the second President of the United States, John Adams. On July 1–3, 1863, a crucial battle of the American Civil War was fought near Gettysburg; Adams County, as a result, is a center for Civil War-related tourism. The county is part of the South Central Pennsylvania region of the state.

Adams County comprises the Gettysburg metropolitan statistical area, which is also included in the Harrisburg–York–Lebanon combined statistical area.

Geography
According to the U.S. Census Bureau, the county has a total area of 522 sqmi, of which 519 sqmi is land and 3.1 sqmi (0.6%) is water. The Borough of Gettysburg is located at the center of Adams County. This county seat community is surrounded on three sides by the Gettysburg National Military Park (GNMP). The Eisenhower National Historic Site adjoins GNMP on its southwestern edge. Most of Adams County's rural landscapes and its mid-19th century roadway pattern remain intact today. Thirteen historic roadways converge at or near Gettysburg Borough. Two circular rings of towns surround Gettysburg; the first is typically found at a distance of approximately 7 mi from Gettysburg. The second ring is found at a distance of 12 to 15 mi from the county seat. This "spokes and wheel" pattern is one of the few examples of Central Place Theory in the Eastern United States.

The county is in the watershed of the Chesapeake Bay and is drained by the Susquehanna and Potomac Rivers.
