Concrete is the world’s most ubiquitous building material, and many important milestones of its development took place in Brooklyn. In this virtual program, we will examine concrete’s history, production, and chemistry, then discuss some of the landmark structures that drove the development of steel-reinforced concrete in the late nineteenth and early twentieth centuries. From Gowanus to DUMBO, Prospect Park to the Brooklyn Navy Yard, we will look at monumental buildings and small details designed by some renowned architects, including Cass Gilbert, Albert Kahn, and Calvert Vaux.
Concrete may seem like an odd material for shipbuilding, but during World War I, severe shortages of steel led to this innovation. Devised by Norwegian immigrants the Fougner brothers, they built one of the first such ships in the US at their shipyard in Flushing, Queens. The technology reached its apex during World War II, when the US built over 100 ships and barges, and they were used as freighters, tankers, and even floating ice cream factories. Large-scale concrete shipbuilding is a thing of the past, but we will examine the fates of these wartime ships, and discuss many examples of concrete boatbuilding today.
Completed in 1919, the Brooklyn Army Terminal is a marvel of architecture and engineering. On this virtual tour, we will examine its design and construction during World War I, its 47-year service as a military supply base, and its reinvention as a hub for industry, manufacturing, and technology today. We will spend time in the breathtaking atrium, step into the skybridges that connect the buildings, and look at how the site has been renovated.
At each of the water passages that lead to New York Harbor – from the Narrows to Hell Gate, Ambrose Channel to the Race – disused forts stand on either shore, once guarding these entrances. In this virtual program, we will explore the history of coastal fortifications in New York from the Revolutionary War to World War II, examining the different eras of fort construction and the technological advancements that drove the changes in these forts’ shape, armament, and role over time. We will also look at how these forts have been repurposed today – as parks, schools, museums, and the last active military base in New York City.
The neighborhood today known as DUMBO was once the center for the agricultural hamlet of Brooklyn, and grew into a center of commerce, shipping, and manufacturing. On this virtual walk, we will look at several eras of the neighborhood’s history reflected in its architecture. From the storage warehouses of the 1860s, to the reinforced concrete industrial buildings of the Gairville complex, to the last remaining tenement building in the neighborhood, we will also examine how these buildings have been repurposed to create one of the most expensive residential and office districts in all of New York City.
In 1881, Spanish engineer Rafael Guastavino arrived in New York City and unveiled his new technology for building self-supporting vaulted tile ceilings. These ceilings are now iconic elements of many New York landmarks, and the city is home to more than 250 of them, more than any other city in the United States. On this virtual tour, we’ll look at many of the ceilings up close, in both grand public buildings and out-of-the-way places, including in Prospect Park, Grand Central Station, Ellis Island, and the Municipal Building, as we discuss this engineering marvel.
Times of war have always brought the biggest transformations to the Brooklyn Navy Yard, and none were bigger than those that took place during World War II. But long before the attack on Pearl Harbor plunged America into the global war, US military planners saw the need to expand the country’s navy in order to fight on two oceanic fronts. A larger navy required larger facilities not just to build ships, but to outfit, service, and repair them. In short, the navy needed more dry docks in more places around the world.
