The Great Serpent Mound, located in Adams County, Ohio, is a prehistoric effigy mound in the shape of a serpent that is more than 1,300 feet long. It is one of the largest effigy mounds in the world and is estimated to have been built by the Adena culture more than 1,000 years ago.
Delaware County, Ohio, located in the central part of the state, has a rich history that dates back to the early 1800s. The area was initially inhabited by Native American tribes, including the Delaware and Shawnee people. In the late 18th century, European settlers began to establish farms and settlements in the region.

Formally established in 1808, Delaware County was named after the Delaware Tribe. The county's early economy was primarily agricultural, with farmers cultivating crops such as corn, wheat, and tobacco. The development of infrastructure, including canals and railroads, boosted commerce and facilitated the transport of goods to larger markets.

Delaware County played a significant role in the abolitionist movement during the 19th century. The town of Delaware, the county seat, was home to several prominent abolitionists, including Harriet Beecher Stowe. The county's location along the Underground Railroad made it an important stop for escaped slaves on their way to freedom in Canada.

The 20th century brought rapid growth and urbanization to Delaware County. The discovery of natural resources, such as oil and gas, led to economic prosperity in the region. The county saw the construction of significant infrastructure projects, including highways and modern utilities, which attracted more businesses and residents.

Today, Delaware County is one of the fastest-growing counties in Ohio, experiencing substantial population growth and ongoing development. While the county continues to embrace its agricultural roots, it is also becoming a thriving suburban community, known for its excellent schools, vibrant local businesses, and beautiful natural scenery.
