The Marietta Museum of History located in Marietta, Georgia. Open since 1996, our museum is housed on the second floor of the historic Kennesaw House. Originally a cotton warehouse built in 1845, it was remodeled to become the Fletcher House Hotel in 1855. During the Civil War the hotel temporarily served as a makeshift hospital and morgue. For this reason, the building has become the subject of many stories and local ghost folklore.
