Designed by John H. Duncan, the architect of Grant's Tomb, the monument is an early example of Beaux-Arts architecture in America. The design is based on "The Monument", a 1671 structure built to commemorate the Great Fire of London, on the London street where the 1666 fire started. The height of the Trenton monument is intentionally the same height as the London monument.

The hollow Roman-Doric fluted column of the monument is constructed of granite, as is the pedestal which supports it, although slightly darker stone was used to give the base the appearance of more solidity. The column is capped by a small, round pavilion, forming an observation deck; accessible by means of an electric elevator, that has provided thousands of tourists an excellent view of the city and the surrounding scene of the battle. Encircling the column, just above the cap, thirteen electric lights, symbolizing the original Thirteen Colonies, shed their radiance at night.

The pavilion is surmounted by an acanthus leaf pedestal where, atop the entire structure, a colossal bronze statue of General George Washington by William Rudolf O'Donovan crowns the monument. Washington is depicted as he appeared at the opening of the engagement and, with his extended right hand, directs the fire of the Continental artillery down King (now Warren) Street. The figure is 13 feet (4.0 m) feet tall, while the monument, including the statue, is 150 feet (46 m) above street level.

On the base of the pedestal are two bronze relief panels by Thomas Eakins depicting "The Continental Army Crossing the Delaware River" and "The Opening of the Battle." The latter panel depicts the battery of Alexander Hamilton about to fire down King Street. A third bronze relief panel, "The Surrender of the Hessians," was modeled by Charles Henry Niehaus. On the north side of the pedestal is a bronze tablet presented by the Society of the Cincinnati of New Jersey.

Guarding the entrance to the monument stand two bronze figures of Continental soldiers by O'Donovan. One is a statue of Private John Russell, a member of Colonel John Glover's Marblehead Regiment of seafaring men from Marblehead, Massachusetts, who gained fame by transporting Washington's army across the ice-choked Delaware River on the night of December 25–26, 1776. The other figure is modeled after a likeness of Private Blair McClenachan, of the Philadelphia Light Horse Troop, a unit which also took part in the battle.

The monument is located in an area of the city known as "Five Points". It was here, at the intersection of Warren (King) Street, North Broad (Queen) Street, Brunswick, Pennington and Princeton Avenues, that the American artillery was placed. From this high vantage point, they dominated the streets of Trenton, preventing the Hessian troops from organizing an effective counterattack.

A movement to erect a monument commemorating the victory at Trenton began in 1843. About forty years later in 1886, the property for the monument was acquired by the Trenton Monument Association. To build the monument, the New Jersey legislature appropriated $15,000, Congress $30,000, and citizens contributed $15,000. Monument Park at the "Five Points" was acquired under the provisions of an ordinance passed June 28, 1893.

The cornerstone was laid Saturday, December 26, 1891, on the 115th anniversary of the Battle of Trenton. The base and pedestal were erected in the spring of 1892, the capstone raised into position on Saturday, August 31, 1893, and the statue of General Washington finally placed atop the shaft September 5 of the same year. The completed memorial was dedicated with elaborate ceremonies on October 19, 1893, the 112th anniversary of the surrender of General Lord Cornwallis at the Siege of Yorktown in Virginia; in attendance were eight governors of the original thirteen states.

Although various changes have taken place in the immediate vicinity of the monument since its dedication, the commanding figure of Washington still looks down upon the city, which has developed from what was a small village in 1776. The monument was listed on the National Register of Historic Places in 1977.^[3]
