The old Anaconda Copper Company smelter stack, completed in 1919, is one of the tallest free-standing brick structures in the world at 585 feet. The inside diameter is 75 feet at bottom, tapering to 60 feet at the top. In comparison, the Washington Monument is 555 feet tall. The stack dominates the landscape like the Company once dominated the area's economic life. Since the smelter closed in 1980, the stack has become a symbol of the challenges that face communities dependent on finite resources.

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.

Logan Elm State Memorial is said to be the site where, in 1774, Chief Logan of the Mingo tribe delivered his eloquent speech on Indian-white relations. The speech was supposedly delivered under a large elm tree. Considered to be one of the largest elms in the U. S., the tree stood 65 feet tall, with a trunk circumference of 24 feet and foliage spread of 180 feet. It died in 1964 from damage by blight and storms. The tree's former location is marked by a plaque. Other plaques and monuments in the park honor Native Americans and early Ohio settlers.

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.
