Castle Williams, New York City

Castle Williams stands as a stoic monument on Governors Island in New York City, New York. This robust, circular fortification, constructed between 1807 and 1811, was designed by architect and engineer Lieutenant Colonel Jonathan Williams, with its primary purpose to defend New York Harbor during the 19th century. Now a testament to military architecture, Castle Williams offers visitors a glimpse into the past and an unparalleled view of the surrounding harbor.

Once a pivotal part of the city's defense system, the fort has been repurposed throughout history, serving as a prison during the Civil War, a storage facility, and later as housing for military families. In its current incarnation, Castle Williams is a public historical site, providing educational tours and exhibitions that tell the tale of its military significance and evolution over the centuries.

For tourists, the monument is a cultural treasure amidst the urban landscape of New York City. Accessible by ferry, visitors can explore the grounds and the interior of the castle, experiencing the thick stone walls and the open courtyard that was once a bustling military hub. The top of the fort offers a panoramic vantage point, where one can absorb the breathtaking views of the Statue of Liberty, Ellis Island, and the skyline of Lower Manhattan.
