Inscription Rock, on the south shore of Kelleys Island, is marked with prehistoric Indian pictographs. The flat-topped limestone slab displays carvings of animals and human figures. Discovered partly buried in the shoreline in 1833, the 32-foot-by-21-foot rock is now entirely exposed. Much eroded by the elements, it is now protected by a roof and viewing platform. Archaeologists believe the inscriptions date from sometime between AD 1200 and 1600.

These stairstep locks, among the best preserved in Ohio, were part of the Miami and Erie Canal System, which opened for navigation in 1845 and connected Cincinnati and the Ohio River to Toledo and Lake Erie. For several decades the canal provided Ohio with valuable transportation and waterpower. Railroads gradually rendered the canals obsolete. The lockmaster's house, now a private residence, and a dry-dock basin for boat repair are still visible. Five locks step down to Loramie Creek where the abutments for the aqueduct remain.

Leo Petroglyph is an outstanding example of prehistoric Indian inscriptions. On the edge of a ravine, the sandstone petroglyph contains 37 incised drawings of humans, animals, and human and animal footprints. It is now protected by a roof and viewing platform. The carvings, whose meaning is unknown, are attributed to Fort Ancient Indians who occupied this area between AD 1000 and 1650.

Buffington Island commemorates the only significant Civil War battle that took place on Ohio soil. Here a Union army routed a column of Confederate cavalry commanded by General John Hunt Morgan in 1863. A monument made of broken Ohio glacial boulders is set in a four-acre outdoor park where visitors can enjoy picnics and read the signs describing the history of the area. It is not on an island.

The flat-topped ceremonial mound—composed of sand, shell, and village debris—measures 100 by 170 feet at the base and is 20 feet in height. Archaeological excavations have disclosed at least three periods of Native American cultures, the earliest dating back 2,000 years.

Built between 1905 and 1912 and named for Jeduthan Baldwin, an engineer for the Colonial army during the Revolutionary War, Fort Baldwin originally consisted of three batteries (Cogan, Hardman, and Hawley). Battery Cogan had two three-inch guns, Battery Hardman had one six-inch disappearing gun, and Battery Hawley had two six-inch pedestal guns. All of these guns were removed in July 1924. During the First World War, Forts Baldwin and Popham held a garrison of two hundred soldiers including the 13th and 29th Coast Artillery.
