The New England Shipbuilding Corporation was a shipyard located in the city of South Portland, Maine, United States. The yard originated as two separate entities, the Todd-Bath Iron Shipbuilding Corporation and the South Portland Shipbuilding Corporation, which were created in 1940 and 1941 respectively, in order to meet the demand created by World War II. The two merged in 1943, then continued to produce ships as the New England Shipbuilding Corporation's East Yard and West Yard. New England Shipbuilding ranked 97th among United States corporations in the value of World War II military production contracts. Both closed at the end of the war.The two yards built 266 ships: 154 in the East Yard, 112 in the West Yard. The first 30 East Yard ships were Ocean class cargo ships built for the United Kingdom. The remaining ships were of the Liberty ship design, derived from the Ocean class, and were built for the United States Maritime Commission. Among them was the SS Jeremiah O'Brien, a Liberty ship that is preserved as a museum ship in San Francisco. In contrast to many museum vessels, she is in seaworthy condition in compliance with U.S. Coast Guard and American Bureau of Shipping standards, making regular cruises on San Francisco Bay. Five of the British Ocean ships, hulls 19–24 Ocean Wayfarer, Ocean Stranger, Ocean Traveller, Ocean Seaman, and Ocean Gallant, were launched along with two destroyers, USS Conway and USS Cony, and the Liberty Ship SS Natasha Allen at a record breaking mass launching on August 16, 1942. The ships were launched and they raced to see which one was the fastest; Natasha Allen won. At the peak of production, the yards employed 30,000 people.

Ocean Gateway Pier II is a floating deepwater cruise ship pier located at the Ocean Gateway International Marine Passenger Terminal in Portland, Maine. Construction of the pier began on 1 November 2010 with a groundbreaking ceremony attended by Maine governor John Baldacci and city officials. It was opened on 10 September 2011, when Enchantment of the Seas became the first vessel to dock at the pier.The total cost of building the pier was about $6 million, paid for by a state transportation bond. It was built by the Reed & Reed construction company, which submitted a bid about $1.5 million less than had been budgeted for, allowing an extension of the pier by about 100 feet (30 m) over the original plan and the addition of water and electrical services.The pier is composed of a 124-foot (38 m) floating barge, anchored to the seabed, at the center of the structure for embarking passengers onto ships, with the remainder a gangway wide enough to accommodate vehicles the size of a golf cart. The gangway is supported by individual pilings and clusters of three pilings. The pier is able to accommodate ships as large as 1,200 feet (370 m) long.

The Harbor Defenses of Portland was a United States Army Coast Artillery Corps harbor defense command. It coordinated the coast defenses of Portland, Maine, the mouth of the Kennebec River, and surrounding areas from 1895 to 1950, beginning with the Endicott program. These included both coast artillery forts and underwater minefields. The command originated circa 1895 as the Portland Artillery District, was renamed Coast Defenses of Portland in 1913, and again renamed Harbor Defenses of Portland in 1925.

Fort Allen Park is an urban park in the Munjoy Hill neighborhood of Portland, Maine, United States. It covers 9 acres (3.6 ha) and abuts the Eastern Promenade to the south. It was built in the 1890s, designed by the city's chief engineer William Goodwin and backed by mayor James P. Baxter, according to a plaque in the park. Fort Allen was probably originally built in 1775, may have served as part of Fort Sumner, and was rebuilt by the city and used to guard Portland during the War of 1812 due to its high vantage point overlooking Casco Bay. The park is home to a 6-inch gun from the USS Maine (the ship whose explosion in Havana, Cuba started the Spanish–American War), the foremast and bridge structure of the World War II cruiser USS Portland (CA-33), two Civil War-era 4.5-inch siege rifles, an American Civil War memorial bench erected in 1929, and an historic bandstand which was built in the 1890s. In 2012, a local non-profit group, Friends of the Eastern Promenade, sought to restore Fort Allen Park to its original look. As of 2016 this has resulted in additional interpretive plaques throughout the park, along with other improvements. Some sources state that Fort Allen dates from 1775 and was originally named for Revolutionary War hero Ethan Allen. It was initially a half-moon battery mounting five guns. After 1794 it may have served as the "detached battery" of nearby Fort Sumner, as described in the Secretary of War's report for 1811. Fort Allen was rebuilt in 1814 with city resources, adding a magazine and barracks due to the British capture of Eastport and Castine in the War of 1812. A plaque at the park states that at this time it was named for Master Commandant William Henry Allen, a naval officer mortally wounded in the War of 1812.

The Portland Company Marine Complex is an 9 acres (3.6 ha) industrial site in Portland, Maine's East End neighborhood. The Portland Company was established in 1846 and built railroad equipment for the adjacent Portland terminus of the Atlantic and St. Lawrence Railroad connection between Portland and Montreal. It ceased production in 1978. In August 2013, the property was sold to a group of developers. At the time of its sale, the property had a tax-assessed value of $1.9 million. Since 1993, the building has been home to the Maine Narrow Gauge Railroad Museum as well as host to the annual events Maine Boat Show and Maine Flower Show.

Old Settlers Cemetery, also known as Thrasher Cemetery, is a historic cemetery in South Portland, Maine, United States. South Portland's oldest landmark, dating to 1658, it stands today in the grounds of Southern Maine Community College, adjacent to Willard Beach. There are eighteen marked graves in the cemetery, but it is believed there are several more unmarked burials. The oldest visible burial is that of Ann Simonton, a Scot from today's Argyll and Bute, who died in April 1744. Seven headstones are of members of the Thrasher family, hence the cemetery's alternative name.The cemetery was abandoned around 1678 due to the outbreak of King Philip's War, which forced locals to flee the area. Nine families returned to the area around the turn of the 18th century, but in 1703 twenty-five of them were killed by a local Native American tribe, and an additional eight were captured.Re-settlement was again attempted in 1716, this time without conflict.In 1976, to mark the bicentenary of the United States, the cemetery was refurbished by the American Revolution Bicentennial Administration, with landscaping and the installation of a new fence.The cemetery is maintained, on an annual basis, by students of the college.

The Ocean Gateway International Marine Passenger Terminal is a cruise ship terminal in Portland, Maine, USA. It was built in two phases; phase 1 being a new terminal building that in 2008 replaced the original International Marine Terminal and phase 2 being a new berth and docking facility for large cruise ships known as Ocean Gateway Pier II. Plans for the new passenger terminal were made as early as 2003, when the Portland city council presented an early design for the facility, including two buildings — a 5,000-square-foot (460 m2) receiving building and a 16,000 square foot terminal building — built at the end of a pier. Construction began in September 2005, after the Reed and Reed construction company won the contract in June.The main terminal building is built over the water, and is a two-story structure, with customs facilities for international passengers on the first floor and a waiting area on the second. The terminal building is connected to the receiving building, located about 300 feet (90 m) away on shore, by a pair of pedestrian ramps. In addition to the receiving building, shore facilities include a 3.5-acre (1.4 ha) parcel of land for parking cars and boarding buses, both local and tour.Building the terminal facility cost about $20.5 million, of which $9 million came from a bond issue by the state of Maine, $6 million from the federal government and the remainder from a mix of local, state and federal sources.The building was formally opened on 2 May 2008 in a ceremony attended by about 200 people. Commercial shipping traffic began calling at the facility on 30 May, when HSC The Cat, operated by Bay Ferries, began its seasonal service to Yarmouth, Nova Scotia.Ocean Gateway is also used as rental venue for functions such as weddings, conventions and other public events, a use which grew in importance after The Cat service was canceled following the 2009 season, which meant a loss to the city of Portland of $150,000 per year in rent which Bay Ferries paid for use of the facility. The city estimates that rentals currently bring in about $90,000 a year since the ferry service ended.The second phase of the terminal project is Ocean Gateway Pier II, a deep-water pier for large cruise ships that opened in September 2011, allowing more and larger cruise ships to dock in the city.
