The Washington Monument in Baltimore has been closed to the public in light of a recent engineering study that found its parapet to be unsafe. CVM Engineering of Philadelphia studied the 178-ft-tall marble monument, which predates the Washington Monument in Washington, D.C., as part of a $200,000 master plan to restore the monument and its surrounding squares. CVM reported that, on the parapet, mortar between slabs was missing and metal support brackets were rust- ed and should be replaced. Engineers recommended $1 million in total repairs, including $300,000 for work on the parapet. The monument, which was completed in 1829, was last renovated in 1992.
