The first cornerstone is laid for Fort Hamilton in New York City.

Fort Hamilton is a historic United States Army installation located in the southwestern part of Brooklyn, New York. Situated on the Narrows, which is the entrance to the New York Harbor, the fort overlooks the waters where the Hudson River meets the Atlantic Ocean. It is the only active-duty military installation in New York City.

Fort Hamilton has a long and storied history. It was initially constructed in 1825 as a coastal fortification to protect New York City from potential invasions. The fort was named after Alexander Hamilton, one of the Founding Fathers of the United States and the first Secretary of the Treasury. The original fort was made of earthworks and included several gun batteries.

Over the years, Fort Hamilton underwent significant renovations and expansions. In the late 19th century, brick and granite structures replaced the original earthen fortifications. These structures include the fort’s iconic entrance, known as the Sentries’ and Officers’ Entrance Gates, which were constructed in 1873 and 1874, respectively.

During World War II, Fort Hamilton played a vital role in the defense of New York Harbor. It served as a base for the U.S. Army’s Harbor Defense Command and housed troops and artillery units responsible for protecting the city from potential attacks. After the war, the fort’s role shifted to supporting the military community and providing logistical support to various units in the area.

Today, Fort Hamilton is primarily a garrison and administrative base for the U.S. Army. It serves as the headquarters for the U.S. Army Garrison – Fort Hamilton, which manages the installation and provides support services to the military personnel and their families stationed there.

The fort is also home to the New York City Recruiting Battalion, responsible for Army recruiting efforts in the city. It hosts a variety of military units, including the Military Entrance Processing Station, the Fort Hamilton Army Education Center, and the U.S. Army Reserve’s 77th Sustainment Brigade.

In addition to its military functions, Fort Hamilton has a strong community presence. The installation features amenities such as schools, a chapel, a commissary, a gymnasium, and recreational facilities. It also offers housing options for military families.

Fort Hamilton’s historical significance and picturesque location make it a popular tourist destination. The fort’s grounds and some of the historic structures are open to the public, allowing visitors to explore the site and learn about its history.
