Redoubt Four

Redoubt Four is an earthwork fortification at West Point reinforced with stone walls positioned on elevated ground. The structure was designed with geometric precision to protect Fort Putnam and the surrounding area from approach by way of Rocky Hill.

The redoubt was designed by engineer Thaddeus Kosciuszko in 1778 as part of the defensive system protecting West Point. It served as an outer fortification to guard against attacks from the lower grounds during the Revolutionary War.

Archaeological excavations during the American Revolution Bicentennial in 1975 revealed details about the original construction methods and military engineering.

The site is accessible on foot as part of walking routes through the West Point grounds. Wear sturdy shoes as the terrain is uneven and can become slippery when wet or muddy.

Benedict Arnold documented the wooden structure's specifications in 1780, noting its 10-foot height and walls ranging from four to five feet thick.
