Established in 1788, Marietta is the oldest city in the state of Ohio, and the first official American settlement territory north and west of the Ohio River. Known as the “Riverboat Town,” it is located at the confluence of the Ohio and Muskingum rivers. Washington County’s earliest visitors arrived more than 2,000 years ago, and today thousands of visitors continue to come to the area each year to enjoy its charm, natural beauty, flowing rivers and rich heritage.

Washington County’s First Residents

The Hopewell and Adena Indian cultures claimed the territory we now call Washington County around 100 BC. Although the cultures had disappeared by AD 500, they left behind 95 acres of earthly artworks. Marietta’s founding fathers detected the importance of the mounds, embankments and passageways the ancient tribes created, and they did their best to preserve them. Today, portions of these ceremonial structures still stand, including the Conus Mound, a 30 foot structure located in the Mound Cemetery.

Around 1650, American Indian tribes came from all directions to vie for the territory where Washington County is now established. Tribes such as the Delaware, Mingo and Shawnee settled here until approximately 1850. These tribes created villages, cultivated crops and made our region their home.


Founding Marietta

Marietta was the first settlement in the Northwest Territory, founded by the Ohio Company of Associates in 1788, led by General Rufus Putnam.

Putnam, considered the founding father of the town, led a group of 48 Revolutionary War veterans from New England to Washington County. The settlers named their new home “Marietta,” in honor of the French Queen Marie-Antoinette, whose nation provided crucial aid in the struggle for American independence. Putnam’s house still stands, protected within the walls of The Ohio River Museum in Marietta.

The people of Marietta left some of the local Indian mounds intact, including one that stood in the center of the town cemetery. The early settlers also built a fortification known as Campus Martius to protect themselves from Native American attacks.


The Underground Railroad

In 1795, Washington County became a small but influential part of the anti-slavery movement. Activists within the county became reliable conductors on the Underground Railroad. The Muskingum River acted as a major byway in the 1800s for travelers on the Underground Railroad. Today, visitors can take a tour of Underground Railroad sites throughout the county, or view a permanent exhibit at the Belpre Historical Society.

America’s Riverboat Town: Yesterday and Today

Because of its location along the Ohio River, Marietta grew quickly. It became a major trading center in the Northwest Territory and later in the state of Ohio. When Ohio sought statehood in 1803, Marietta lobbied to become its first capital city, losing out to Chillicothe, but Marietta was still the main point of entry into the state. In 1811, as steamboats began to churn in America’s river waters, Washington County entered a boom era, bolstered by settlers passing through, ship-building, and commerce.

The riverboat legacy lives on in Marietta. Every year, the weekend after Labor Day, the Ohio River Sternwheel Festival brings crowds and sternwheelers of all sizes from throughout the country to Marietta to celebrate the riverboat era and heritage. Visitors enjoy sternwheeler races, an antique car show, and many other events.

From spring through the beautiful autumn season, The Valley Gem Sternwheeler offers river cruises to visitors. The W.P. Snyder Jr., the only steam-powered sternwheel towboat still afloat in the United States, is moored behind The Ohio River Museum.

Washington County Today

Many historical sites have been beautifully preserved within Marietta and Washington County, reminding all residents and visitors that America’s westward expansion began in our small but mighty, riverboat town. Marietta remains a political and cultural center, and many tourists visit each year to find out about the city’s important place in Ohio’s early history.
