Current use

From 1944 through 2007, Glendower was operated and maintained by the Ohio Historical Society. On December 3, 2007, it was transferred to the Warren County Historical Society, which ran the site until August 2022 as a museum.^[3]

Glendower sold in the fall of 2022 to a private buyer but the sale fell through when the buyer backed out and went on sale again in January 2023, with all restrictive Governor Deed covenants that limited its use removed.^[4]

The grounds of Glendower were often used by Civil War reenactors.
