Any local history buff knows that Marietta is full of history, but the Ohio Historical Society wants to make sure other people have a chance to learn about the town's past.
"As much as we'd like to save the buildings and so forth, it's just not possible," Henry Burke, a historian, said.
Burke worked hard to make sure people still have a way to learn about the past.
"That's going to be there for a long time, so we try to make it as accurate as possible," Burke said.
He's talking about an historic marker that was placed in Marietta as a way to tell one of the area's greatest stories.
"By Marietta being the earliest settlement in the northwest territory, the underground railroad blossomed right here along the Ohio River."
And that wasn't the only marker being dedicated.
"It's been a long time coming since we've honored Catherine Fay Ewing in this manner," Nancy Sams, President of the Belpre Historical Society, said.
Ewing along with Francis Dana Gage, two women who spoke against slavery, got their recognition.
"There's so much history and it's really hard to condense it to these markers and hopefully once we get these done, there will be others that we can do throughout the state," Sams said.
These are just two historical markers that were dedicated.
A total of seven markers are being placed in the area.
