Originally known as Allen’s Mill Bridge, the Eldean Covered Bridge was built over the Great Miami River in 1860 for Miami County by the Hamilton Brothers of nearby Piqua. Its 224 feet place it among Ohio’s longest covered bridges and the longest in the nation that follows an 1830 Stephen H. Long patent, considered America’s first science-based bridge design. The Long system added strength through a series of hand-driven wedges. Placed on the National Register of Historic Places in 1975, the bridge was restored in 2005/2006.

In March 1884, public confidence of Cincinnati law enforcement was extremely low. The public believed that murderers and other serious offenders were not brought to justice promptly or received little punishment. Civil unrest was brought to a boil when a seventeen-year-old was sentenced to only twenty years for manslaughter after brutally murdering his employer. On March 28, thousands of citizens stormed the county jail and courthouse. The riots lasted three days requiring forces from the Sheriff’s Office, city police, and local and state militia to restore order. Fifty-four people were killed and more than 200 wounded. The courthouse and jail suffered enormous damage, and valuable records were destroyed from the assault and fire. The riot gained international notoriety and helped pave the way for removal of political favoritism and a larger police force.

In 1837, Cincinnati merchants projected a branch canal to join the Whitewater Canal at West Harrison, Indiana, with the goal of tapping commerce from Indiana’s Whitewater Valley. The major obstacle on this route was the ridge between North Bend and Cleves, just northeast of this site. Engineer Darius Lapham designed a 1,782-foot tunnel though this barrier. Lined with brick made on site, the tunnel, 24 feet wide and 20 1/2 feet high, was the first canal tunnel in Ohio. Six workers died in its construction. The Cincinnati & Whitewater Canal opened in 1843 but was abandoned by 1856, after the main Whitewater Canal had been rendered useless by repeated flooding. The canal tunnel was subsequently used as a railroad tunnel from 1863 until 1888, illustrating the progression of transportation technology in the mid-nineteenth century.

Carlisle Station Depot. The Carlisle depot for the Cincinnati, Hamilton & Dayton (CH&D) railroad was located nearby. The CH&D started operations in 1851 and was the second railroad through Warren County. Carlisle Station was a passenger and freight-shipping depot and was joined in 1872 by another, when Cincinnati & Springfield Railroad (later part of the Big Four and the New York Central Railroads) erected a depot in nearby Franklin. Carlisle was originally known as the “Jersey Settlement,” because many settlers in the early 1800s were from New Jersey. George Carlisle, vice-president of the CH&D, purchased a large tract of land here. After Carlisle and his wife Sarah donated a lot to the community in 1856, residents renamed the place “Carlisle Station.” The Carlisle Literary Association built a hall on the lot c. 1856, which, as of 2019, remains as the older section of Carlisle’s municipal building.

Border warfare characterized the American Revolution on the northwest frontier. Between August 26 and September 15, 1781, sixty-four survivors of Lochry’s Expedition were held captive by “Butler’s Rangers” (British-allied Indians led by George Girty) in a camp near this site. Colonel Archibald Lochry’s battalion of Pennsylvania militia, part of a larger punitive expedition under General George Rogers Clark and traveling down the Ohio River behind the main force, was attacked by Girty’s men ten miles downstream from the mouth of the Great Miami River near present-day Aurora, Indiana. Thirty-seven militiamen were killed in the August 24 battle, including Lochry, and the rest captured. Afterwards Rogers abandoned his objective of capturing British-held Detroit. The captives were taken to Detroit and eventually to Montreal. Tradition holds that fewer than twenty of Lochry’s battalion ever returned to their homes.

Butler County was created on March 24, 1803, about three weeks after Ohio became a state. Hamilton won the competition for the county seat, thanks to Israel Ludlow, Hamilton’s founder. Ludlow’s donation of the public square secured the county seat. The first Butler County trial court met in July 1803 in a tavern before moving to a two-story military building located at what had been Fort Hamilton (1791-1796). The county built the first courthouse on this public square in 1810. The two-story stone building contained a jail on the first floor and a courtroom on the upper level. A new brick two-story courthouse was built on this square in 1817 at a cost of $10,000. A four-sided clock was added to the top of the building in 1837. (continued on other side)

Cincinnati, along with Milwaukee and St. Louis, is one of the three corners of the “German Triangle,” so-called for its historically high concentration of German-American residents. During the 19th century, Cincinnati was both a destination for immigrants to the tri-state area and a hub from which many groups of Germans moved inland to settle new Ohio communities-many along the Miami and Erie canal corridor which began here. German-Americans have greatly influenced the social, cultural, economic and political life of the Cincinnati area. At the turn of the 21st century, approximately half of Cincinnati’s population was of German descent. (Continued on other side)

Prompted by response to his popular lectures, astronomer Ormsby MacKnight Mitchel (1809-1862) founded the Cincinnati Astronomical Society (CAS) in 1842. With CAS funding, Mitchel traveled to Munich, Bavaria, to acquire the optical elements for what became the world’s second largest refractor telescope. In 1843 former president John Quincy Adams laid the cornerstone of the observatory building, located upon the hill since known as Mount Adams. The Cincinnati Observatory was completed and opened for study in 1845. Mitchel, who died in service during the Civil War, was among the first to popularize astronomy in America. The telescope he brought to Cincinnati remains in daily use, the oldest such instrument in the United States.
