Welcome to Marietta, Ohio

Marietta is a historic and elegant town nestled at the confluence of two rivers. Visitors come to wander our shady brick streets and gaze at Victorian mansions. They love to browse for antiques and make merry in our bars and restaurants.

But there is another Marietta, a city few visitors see. A Hidden Marietta exists just below the surface of ordinary life. It is a place where the past bleeds into the present and the line that separates the living from the dead blurs.

Do you believe in ghosts?

Many Marietta residents do. The entire town is a paranormal hot spot. No one really knows why. Perhaps it’s the layers of history and the lasting impact of the people who lived and died here. Or it could relate to the ancient Hopewell and Adena people whose mysterious mounds dot the city. Whatever the reason, Marietta has more than its share of restless spirits. Curious? Join us for an evening Ghost Trek.

Ancient Magic

More than 2000 years ago the most sophisticated people in North America built grand pyramids, mounds and enormous geometric enclosures in the place we now call Marietta. Time and “progress” have destroyed portions of the original complex, but sacred places have a way of surviving. Join us on a guided walking tour of Marietta’s Ancient Earthworks.
