The OES visited Marietta in Washington County on June 16, 2001. We originally visited the town to take photographs of the Indian mounds and a cemetery there, but we were so intrigued by all of the historical places that we decided to take a few pictures of them. Listed next to each photo is a brief description of the location. Marietta is a must-visit town if you are in to history and historical places. It seemed like every time we turned around, we bumped in to another historical plaque.
