Fort Schuyler is a preserved 19th century fortification in the New York City borough of the Bronx. It houses a museum, the Stephen B. Luce Library, and the Marine Transportation Department and Administrative offices of the State University of New York Maritime College. It is considered one of the finest examples of early 19th century fortifications. The fort was named in honor of Major General Philip Schuyler of the Continental Army.
Fort Knox, now Fort Knox State Park or Fort Knox State Historic Site, is located on the western bank of the Penobscot River in the town of Prospect, Maine, about 5 miles (8.0 km) from the mouth of the river. Built between 1844 and 1869, it was the first fort in Maine built entirely of granite; most previous forts used wood, earth, and stone. It is named after Major General Henry Knox, the first U.S. Secretary of War and Commander of Artillery during the American Revolutionary War, who at the end of his life lived not far away in Thomaston. As a virtually intact example of a mid-19th century granite coastal fortification, it was added to the National Register of Historic Places in 1969 and declared a National Historic Landmark on December 30, 1970. Fort Knox also serves as the entry site for the observation tower of the Penobscot Narrows Bridge that opened to the public in 2007.
The Rodman gun is any of a series of American Civil War–era columbiads designed by Union artilleryman Thomas Jackson Rodman (1815–1871). The guns were designed to fire both shot and shell. These heavy guns were intended to be mounted in seacoast fortifications. They were built in 8-inch, 10-inch, 13-inch, 15-inch, and 20-inch bore. Other than size, the guns were all nearly identical in design, with a curving bottle shape, large flat cascabels with ratchets or sockets for the elevating mechanism. Rodman guns were true guns that did not have a howitzer-like powder chamber, as did many earlier columbiads. Rodman guns differed from all previous artillery because they were hollow cast, a new technology that Rodman developed that resulted in cast-iron guns that were much stronger than their predecessors.
Fort McClary is a former defensive fortification of the United States military located along the southern coast at Kittery Point, Maine at the mouth of the Piscataqua River. It was used throughout the 19th century to protect approaches to the harbor of Portsmouth, New Hampshire and the Portsmouth Naval Shipyard in Kittery. The property and its surviving structures are now owned and operated by the State of Maine as Fort McClary State Historic Site, including a blockhouse dating from 1844.
The Parrott rifle was a type of muzzle-loading rifled artillery weapon used extensively in the American Civil War.
House Island is a private island in Portland Harbor in Casco Bay, Maine, United States. It is part of the City of Portland. The island is accessible only by boat. Public access is prohibited, except for an on-request tour sanctioned by the island's owners. House Island includes three buildings on the east side and Fort Scammell on the west side. The buildings are used as vacation rentals and other summer residences. The island's name derives from the site of an early European house, believed that built by Capt. Christopher Levett, an English explorer of the region.
The columbiad was a large-caliber, smoothbore, muzzle-loading cannon able to fire heavy projectiles at both high and low trajectories. This feature enabled the columbiad to fire solid shot or shell to long ranges, making it an excellent seacoast defense weapon for its day. Invented by Colonel George Bomford, United States Army, in 1811, columbiads were used in United States seacoast defense from the War of 1812 until the early years of the 20th century. Very few columbiads were used outside of the U.S. and Confederate Armies; nevertheless, the columbiad is considered by some as the inspiration for the later shell-only cannons developed by Frenchman Henri-Joseph Paixhans some 30 years later.
Several boards have been appointed by US presidents or Congress to evaluate the US defensive fortifications, primarily coastal defenses near strategically important harbors on the US shores, its territories, and its protectorates.
Fort Washington, located near the community of Fort Washington, Maryland, was for many decades the only defensive fort protecting Washington, D.C. The original fort, overlooking the Potomac River, was completed in 1809, and was begun as Fort Warburton, but renamed in 1808.

Fort Independence is a granite bastion fort that provided harbor defenses for Boston, Massachusetts, located on Castle Island. Fort Independence is one of the oldest continuously fortified sites of English origin in the United States. The first primitive fortification was called "The Castle", placed on the site in 1634. It was rebuilt twice, then replaced around 1692 with a more substantial structure known as Castle William. It was abandoned by the British during the American Revolution, but the Americans renamed it Fort Adams and then Fort Independence. The existing granite fort was constructed between 1833 and 1851. Today it is preserved as a state park and fires occasional ceremonial salutes. Fort Independence was added to the National Register of Historic Places in 1970.
Seacoast defense was a major concern for the United States from its independence until World War II. Before airplanes, many of America's enemies could only reach it from the sea, making coastal forts an economical alternative to standing armies or a large navy. After the 1940s, it was recognized that fixed fortifications were obsolete and ineffective against aircraft and missiles. However, in prior eras foreign fleets were a realistic threat, and substantial fortifications were built at key locations, especially protecting major harbors.
Siege artillery is heavy artillery primarily used in military attacks on fortified positions. At the time of the American Civil War, the U.S. Army classified its artillery into three types, depending on the gun's weight and intended use. Field artillery were light pieces that often traveled with the armies. Siege and garrison artillery were heavy pieces that could be used either in attacking or defending fortified places. Seacoast artillery were the heaviest pieces and were intended to be used in permanent fortifications along the seaboard. They were primarily designed to fire on attacking warships. The distinctions are somewhat arbitrary, as field, siege and garrison, and seacoast artillery were all used in various attacks and defenses of fortifications. This article will focus on the use of heavy artillery in the attack of fortified places during the American Civil War.
Fort Taber District or the Fort at Clark's Point is a historic American Civil War-era military fort on Wharf Road within the former Fort Rodman Military Reservation in New Bedford, Massachusetts. The fort is now part of Fort Taber Park, a 47-acre town park located at Clark's Point. Fort Taber was an earthwork built nearby with city resources and garrisoned 1861-1863 until Fort Rodman was ready for service.
Fort Willard is a former Union Army installation now located in the Belle Haven area of Fairfax County in the U.S. state of Virginia. It is currently undergoing preservation treatment to protect its earthen walls and trenches.
Blakely rifle or Blakely gun is the name of a series of rifled muzzle-loading cannon designed by British army officer Captain Theophilus Alexander Blakely in the 1850s and 1860s. Blakely was a pioneer in the banding and rifling of cannon but the British army declined to use Blakely's design. The guns were mostly sold to Russia and the Confederacy during the American Civil War. Blakely rifles were imported by the Confederacy in larger numbers than other Imported English cannon. The State of Massachusetts bought eight 9 in (23 cm) and four 11 in (28 cm) models.
