Battery Weed is an extraordinary example of military architecture of the second half of the nineteenth century. Located at the water’s edge on the Narrows, this massive masonry fortification was built between the years 1847 and 1861. Constructed of solid slabs of granite, the sea wall of the Battery is six feet thick. At the height of its glory Battery Weed was one of the most powerful forts on the eastern seaboard. In 1862, it mounted between 140 and 150 cannon and was manned by a largo force from the Fifth Regiment, New York Volunteers Artillery.
