The Brooklyn Army Terminal is an architectural and engineering marvel that is today a center of manufacturing and innovation on Brooklyn’s Sunset Park waterfront. Built to supply American forces in World War I, this enormous Cass Gilbert-designed complex served as a supply base for the American military for nearly fifty years, employing more than 20,000 people during World War II. Today, this thriving industrial park is home to over 100 companies in a wide array of industries, from precision manufacturers to biotech researchers, online retailers to chocolatiers. On Saturday, October 21st, and Sunday, October 22nd, 45-minute guided tours of the Terminal’s stunning atrium will be offered on the hour at 12pm, 1pm, 2pm, 3pm, and 4pm. Learn key details about the site’s past, present, and future from NYCEDC’s partner Turnstile Tours. Tours will meet in the North Lobby of Building B. BAT will also have open access Saturday and Sunday, 12pm–6pm.
