This 352-foot (107 m) tall memorial commemorates Commodore Oliver Hazard Perry's September 10, 1813 naval victory over British ships in the Battle of Lake Erie in the War of 1812. Construction of the monument began in 1912 and it opened to the public on June 13, 1915. It is made up of 78 layers of pink granite, topped with an eleven short ton (10 metric ton) bronze urn. The remains of six naval officers, three British and three Americans, were interred beneath the floor of the monument's rotunda.
