Fort New Casco
(1698 - 1716), Falmouth Foreside FORT WIKI
A large 70-foot square earthwork and palisaded fort, also known as Casco Fort (2), with an Officers' quarters, storehouse, and guardhouse. It was attacked by the French in August 1703, rebuilt and enlarged in 1705 as an oblong square 250 feet long and 190 feet wide, with a supporting blockhouse at the shoreline. It was demolished by the Massachusetts government due to budget cuts. Some earthworks may still exist on private property opposite Pine Grove Cemetery on Foreside Road (ME 88).


¤¤ Fort Loyal
(1676 - 1690, 1742, 1775), Portland FORT WIKI
A palisaded log fort. Also spelled Loyall. Rebuilt and enlarged with four blockhouses and eight guns in 1690, commanded by Capt. Simon Willard with 60 soldiers (aka Casco Garrison (1)), but could not withstand the attack by the French in May 1690, and was destroyed. Eventually rebuilt and renamed Falmouth Fort in 1742, located at the foot of present-day India Street. A 1936 plaque is located on the side of a modern water-front building.

An earthwork was built here in 1775, called the Lower Battery. Nothing remains. Nearby were the Upper Battery (1776) at the upper end of Free Street, and Magazine Battery (1776) at Monument Square. Neither exists today.

¤¤ Fort (Ethan) Allen (park)
(Friends of the Eastern Promenade)
(1775, 1814 - 1815), Portland FORT WIKI
Originally a Patriot five-gun half-moon battery in 1775. Rebuilt by the state militia in 1814, it was enlarged and enclosed with a magazine and barracks. The earthworks still remain at the Eastern Promenade at Fore Street. Two 1867 seige guns were placed there much later for display purposes.

¤¤ Fort Lawrence
(1814 - 1815), Portland
Earthwork fort built by the state militia below Fort Allen at Fish Point. No longer exists. A "Third System" fort was later proposed for this location.

¤¤ Fort Sumner
(Munjoy Hill Park)
(1794 - 1820 ?), Portland FORT WIKI
This was the first Federal fort built in Maine, and the only Federal defense of the area until Forts Preble and Scammel were built in 1808. It had a blockhouse, magazine, and barracks, with a Water Battery and brick Gun House (1808). Built on the site of Great Fort of 1775. Rebuilt in 1798 and 1808 as a five-gun battery. No longer in use after the War of 1812, the blockhouse was finally demolished in the 1840's. No remains, located at 60 North Street.

¤¤ Fort Burrows
(1813 - 1815), Portland
A state militia fort located at 58 Fore Street, near Mountfort Street, at Jordan's Point. No remains left.

Located here in 1675 was the George Munjoy Garrison. It was attacked during King Philip's War in 1676, and was probably destroyed in the 1690 attack of the town. Munjoy had died previously in 1680.

A Civil War training camp. Undetermined location.

Camp Berry
(1861 - 1865), South Portland FORT WIKI
A Civil War recruitment and training camp originally located on Mackworth (Mackey's) Island at the mouth of the Presumpscot River in Falmouth, known as Camp Butler. It was relocated to the Cape Elizabeth Trotting Park in 1862, located along Long Creek and the Fore River in Ligonia, and was renamed Camp King and later Camp Abraham Lincoln. Renamed again in 1863. The post hospital was established on Mackey's Island in August 1863, then relocated to Camp Berry proper in November 1863. The hospital was closed in September 1865. Eleven two-family houses were used as Officers' quarters, and ten one-story wooden barracks were built for the enlisted men. The site became the location of the Portland Rolling Mills in 1866. Several of the houses and/or barracks remained in use for factory workers. The site is now a modern tank farm at the end of Lincoln Street, near the Veterans Memorial Bridge (US 1).

Harbor Defense of Portland - FORT WIKI

¤ Fort Preble
(Portland Harbor Museum)
(Southern Maine Community College)
(1808 - 1947), South Portland
Originally this was a 14-gun star-shaped earthwork and stone fort. Built on the site of Patriot Spring Point Battery from 1776, which was renamed Fort Hancock in 1778. The 12-gun North Battery and 10-gun South Battery were built in 1845 and rebuilt again (33 guns total) in the 1870's with new magazines. The South Battery was enlarged to 24 guns in 1887. The outer casemates along the seawall were built in 1863, and the brick face of the old fort was covered with granite. The fort was unsuccessfully attacked in June 1863 by a Confederate raider ship, the Archer. Seacoast batteries here were Battery Kearny (1901 - 1942) destroyed, Battery Chase (1901 - 1942) destroyed, Battery Rivardi (1906 - 1917) built on top of the old fort, Battery Mason (1906 - 1942), and New Battery Mason (1942 - 1946) eroded away from the cliff face. AA Battery #1 (1921 - 1945) was emplaced on Battery Rivardi. A detached 37mm AMTB battery (Battery 361) was also located on post during WWII. Many of the post buildings are still in use by Southern Maine Community College, which acquired the land in 1952. The remaining concrete support shaft of the former Fort Command observation station (1906) is now a Coast Artillery Memorial. The former Ordnance Machine Shop (1902) is now used by the Portland Harbor Museum. The Spring Point Ledge Lighthouse was built in 1897, and the stone breakwater was built in 1951.

Now the Portland Regency Hotel, only a portion of the Head House is original.

¤ Fort Gorges
(1857 - 1946), Hog Island Ledge FORT WIKI
Construction of this hexagonal fortress was never fully completed, nor was it ever fully garrisoned. Several new gun platforms were built on the parapet in the 1870's. A torpedo (mine) storehouse was built in 1901. The fort was still kept on the Army rolls until WWII. A unmounted 10-inch Parrott gun is still located on the parapet. The fort is now owned by the city of Portland, but no regular public transportation is currently available. Tours can be arranged.

¤ Fort Scammell
(1808 - 1898/1946), House Island
Originally a six-gun octagonal blockhouse, with a semi-circular 15-gun earthwork battery and a lunette battery, which were connected in 1845. It was enlarged with three bastions (fourth never built) during the Civil War to mount up to 17 guns. Additional work was done in the 1870's. It was used through the Spanish-American War. A lighthouse / navigation light was built here in 1914. A two-gun AA battery was located here in 1929 - 1939. The island was also the site of an immigration quarantine station from 1907 to 1937.
