Along the waterfront in Brooklyn’s Sunset Park neighborhood stands one of New York City’s most extraordinary examples of early 20th-century industrial architecture: the Brooklyn Army Terminal. While the enormous complex is impressive from the outside, its most remarkable feature is hidden within Building B, where a cavernous, eight-story atrium, towering concrete columns, staggered balconies, and old railroad tracks create a scene that looks almost like something out of a science fiction movie. It is an astonishing piece of engineering, a reminder of an era when American industry built on a truly monumental scale.
Construction of the Brooklyn Army Terminal began in 1918, during the final months of World War I. The United States Army needed a massive transportation and supply center capable of moving troops, weapons, equipment, and other military supplies from American railroads onto ships bound for Europe. The complex was designed by renowned architect Cass Gilbert, whose other famous works include New York City's Woolworth Building and the United States Supreme Court Building in Washington, D.C. Unlike those highly ornamented landmarks, however, the Brooklyn Army Terminal was designed almost entirely around functionality, efficiency, and the movement of enormous quantities of cargo. Completed in September 1919, after World War I had already ended, the complex was among the largest reinforced-concrete structures ever constructed at the time.
Building B was the architectural centerpiece of the terminal. Its most spectacular feature was a gigantic central atrium running nearly the entire length of the building, surrounded by eight stories of concrete loading platforms. Rather than having balconies stacked directly above one another, Gilbert designed them in an alternating, staggered arrangement. This unusual configuration allowed enormous overhead traveling cranes to lift cargo from railroad cars below and deposit it directly onto loading platforms at different levels. Two massive five-ton electric cranes traveled along tracks high above the atrium floor, moving supplies throughout the building. Freight trains could actually enter the structure itself, where their cargo was unloaded and distributed throughout the warehouses. Elevated bridges connected the buildings, while nearby waterfront piers allowed supplies to be transferred directly onto waiting ships. It was an incredibly advanced transportation system for its time, essentially an enormous mechanical machine designed to move the materials of war.
Although the terminal was completed too late to make a significant contribution to World War I, it became absolutely essential during World War II. The complex served as headquarters for the New York Port of Embarkation, a vast military transportation network responsible for moving American troops and supplies overseas. More than 20,000 military and civilian workers were employed at the terminal during the war years, with some accounts placing peak employment even higher. The wider port operation handled approximately 3.2 million troops and 37 million tons of military cargo during the conflict. Day and night, trains arrived, cranes operated, trucks moved equipment, and ships departed the waterfront carrying everything from am******on and vehicles to food, clothing, and medical supplies. For countless American servicemen, the Brooklyn waterfront was one of the last places they saw before heading overseas.
One of the terminal's most famous moments came in September 1958, when a young Elvis Presley departed from Brooklyn aboard a military transport ship bound for Germany. Already one of the biggest musical stars in America, Presley was serving in the United States Army and was being sent overseas for military duty. His departure attracted enormous attention from reporters, photographers, and fans. It remains one of the more unusual chapters in the terminal's history, connecting this massive industrial complex to one of the most recognizable entertainers of the 20th century.
Following World War II, the Brooklyn Army Terminal continued serving military needs throughout the early Cold War. However, changes in shipping technology gradually made its enormous infrastructure less practical. The development of standardized shipping containers, modern cargo-handling equipment, and newer port facilities reduced the need for the elaborate system of railroad tracks, cranes, and staggered loading platforms that had once made Building B so revolutionary. The Army closed the installation as a military base in 1966, although government agencies and private businesses continued using portions of the complex into the early 1970s.
As activity declined, enormous sections of the terminal became underused, and the aging buildings entered a period of uncertainty. Building B's once-bustling atrium grew quiet, its cranes sat idle, and the railroad tracks that had carried thousands of freight cars gradually became obsolete. Although the terminal was never completely abandoned in the traditional sense, portions of the property experienced the deterioration and neglect familiar to so many former industrial and military facilities. Its tremendous size made demolition expensive, while converting millions of square feet of aging warehouse space into something useful presented an equally enormous challenge. For a time, the future of the complex was far from certain.
Fortunately, the Brooklyn Army Terminal escaped the wrecking ball. New York City purchased the property from the federal government in 1981, recognizing its potential as a center for manufacturing, warehousing, and commercial activity. A massive redevelopment effort began during the 1980s, with Building B among the first areas targeted for rehabilitation. Aging mechanical systems were replaced, elevators were modernized, utilities were upgraded, and enormous warehouse floors were divided into spaces suitable for smaller industrial tenants. Rather than demolishing the historic structures, the city adapted them for an entirely different economic era. The terminal was also added to the National Register of Historic Places in 1983, recognizing its architectural and historical significance.
Perhaps the most remarkable aspect of the redevelopment was the decision to preserve Building B's extraordinary central atrium. Although freight trains no longer enter the building and its enormous overhead cranes are no longer operational, much of the original industrial infrastructure remains intact. The old cranes still hang high above the floor, while the staggered concrete balconies continue to overlook the enormous open space. Railroad tracks remain embedded in the ground, and faded markings identifying destinations such as Greece, India, South America, and the Azores can still be found throughout the atrium. Even an old Long Island Rail Road passenger car was placed inside the space as a historical curiosity. The result is an almost surreal combination of functioning modern industrial space and preserved military transportation history.
Today, the Brooklyn Army Terminal is one of New York City's most successful examples of adaptive reuse. Managed by the New York City Economic Development Corporation, the 59-acre waterfront campus contains more than 4.3 million square feet of space and accommodates over 100 businesses employing approximately 3,500 people. Its tenants represent a wide variety of industries, including advanced manufacturing, food production, biotechnology, fashion, creative businesses, and climate technology. New tenants continued moving into the complex in 2026, demonstrating that this century-old industrial giant still has an important economic role to play. The terminal also hosts cultural events, public art, and community activities, while its historic atrium and waterfront public spaces can be visited by the public.
For those fascinated by abandoned industrial architecture, Building B is particularly interesting because it looks like a place that should have been left behind decades ago. Its immense concrete interior, silent cranes, weathered railroad tracks, and seemingly endless rows of balconies possess the atmosphere of a forgotten industrial ruin. Yet, unlike so many comparable structures throughout the Rust Belt and elsewhere, it never became another casualty of demolition or permanent abandonment. Instead, it was given a second life without sacrificing the architectural features that made it extraordinary in the first place.
The Brooklyn Army Terminal is a reminder that enormous industrial buildings do not necessarily have to become obsolete simply because the industries or technologies that created them have disappeared. Sometimes, the best way to preserve history is to give an old building a new purpose while allowing its original character to remain visible. More than a century after its construction, Building B still stands as a magnificent monument to American engineering, military logistics, and the possibilities of historic preservation. It is proof that even the most imposing industrial giants can find new life when someone recognizes their potential rather than simply seeing an outdated building occupying valuable real estate.
I had the chance to revisit this massive work of industrial art in the summer of 2025. The day was perfect and the light was in just the right time of the day to achieve some amazing shadows. If you are ever in the Brooklyn area, definitely stop by and have a look at this amazing structure (and YES, it did appear in both the first and second season of the TV show "Fallout," acting as an HQ of the Enclave!). Have a great Saturday, all and enjoy the view! -Mr. P.
