BALTIMORE (AP) — The city of Baltimore will install interpretive signs next to the city’s four Confederate monuments to add historical context.

Local news organizations report that Mayor Stephanie Rawlings-Blake announced the move Wednesday, months after a commission recommended that some of the monuments be removed.

The mayor appointed the commission last year to study the monuments. In January, it recommended that that a statue of Robert E. Lee and Thomas. J. “Stonewall” Jackson be offered to the National Park Service. It also called for the removal of a statue of Roger B. Taney.

Rawlings-Blake says the installation of the signs is a practical solution to a complicated problem. She says removing the monuments altogether would be an expensive project.
