Near this area, a wooden picket fort was constructed around 1831 by Mexican forces in anticipation of trouble with Anglo immigrants. The fort apparently was named for a camp of Lipan Apaches in the vicinity. In 1835, the small guard force that held the fort surrendered it to Texan forces without a shot being fired. In 1842, a battalion of Texas volunteers camped in this area. In an attempt to lay claim to the territory between the Nueces River and the Rio Grande, the camp was seized by Mexican general Antonio Canales, but the Mexican forces later retreated. Around 10 years later, during the Mexican War, troops under General Zachary Taylor passed through this area on their way to the Rio Grande.

This site marks the birthplace of Walhalla. The town was first called St. Joseph after a mission established near Pembina in 1848 by Father George Belcourt. An original trading post built by trader Norman Kittson in 1851 was later moved to the site. There is a marker on the site.

Fannin Battleground State Historic Site encompasses more than 13 acres. On March 20, 1836, at this site, Colonel J. W. Fannin and 284 of his men surrendered after the Battle of Coleto to Mexican General Jose Urrea and were told they would be treated as prisoners of war. Seven days after the capture, General Santa Anna had Fannin and the men with him, plus other prisoners captured in the area, executed as traitors. Twenty-eight prisoners escaped but 342 men were massacred near what is now Goliad State Park.

Fort Constitution State Historic Site is located on a peninsula on the northeast corner of New Castle Island. It overlooks both the Pisquatua River and the Atlantic Ocean. Fort Constitution is one of seven forts built to protect Portsmouth Harbor. The earliest forts were built to protect the colonists. As Portsmouth Harbor's importance increased with the Revolutionary War shipbuilding industry and the establishment of the Portsmouth Naval Shipyard in 1800, additional fortification was needed. Following the Spanish American War (1898) the improved defense of key harbors became a national priority. Fortifications such as Fort Constitution were constructed on both coasts during the Endicott Period (1890–1920) and at Forts Stark, McClary, and Foster.

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.

Fort Washita was established in 1842 as the southwestern-most post in the United States. (Beyond the borders to the south and west was the Republic of Texas which had recently won its independence from Mexico.) The purpose of the post was to protect the Chickasaw and Choctaw Indians from the Plains Indians. For centuries the latter had used this area for hunting and were not happy with newcomers settling in the area. Troops stationed at Fort Washita from time to time in the 1840s included the 2nd Dragoons, the U.S. Regiment of Riflemen, the 6th Infantry, the 7th Infantry, and the 5th Infantry. During a portion of the 1850s the post served as the United States Army Field Artillery School. Throughout the 1840s and 1850s the post provided quarters for the United States Indian Agency to the Chickasaw and Choctaw governments. On April 16, 1861, the fort was abandoned by U.S. forces under the command of Colonel William Emory. The next day Fort Washita was occupied by Confederate forces and used during the War Between the States. For the next hundred years, the buildings were used by members of the Colbert family who were leaders of the Chickasaw Nation. The fort was acquired by the Oklahoma Historical Society in 1962 and has been designated as a National Historic Landmark.
