Begun in September of 1929, Bowman's Hill Tower was completed in June of 1931 as a commemorative monument to George Washington and his army. Bowman's Hill Tower stands approximately 380 feet above sea level. The Tower itself is 125 feet tall and the base measures 24 square feet. On a clear day, the view from Bowman's Hill Tower encompasses a minimum 14 mile radius of the Delaware River Valley. Bowman's Hill Tower is open seasonally and is included in the Park's admission price. On a clear day, one can see to Trenton, New Jersey, and realize the magnitude and distance of the march Washington and his soldiers undertook in December of 1776.

Bowman's Hill Tower was built of native stone gathered from Bowman's Hill and nearby stone fences. The cut stone used for the sills and balustrades came from local quarries located in Lumberville, Pennsylvania and Lawrenceville, New Jersey. Over 2,400 tons of materials were used in the construction, including: 1,200 perch of stone, 517 tons of sand and 225 tons of cement. An excavation 15 feet deep was made so that the base rests on a foundation of native rock. The construction of the Tower was accomplished entirely by the employees of the Washington Crossing Park Commission. Including labor and materials, Bowman's Hill Tower cost $100,000 to build.

In the early 1980s, Bowman's Hill Tower underwent an extensive restoration and an elevator was installed. Previously visitors climbed a spiral staircase to the observation point at the top of the Tower. Today an elevator takes visitors three-quarters of the way up, opens onto a landing, followed by a twenty-three step climb to the top. The view of the ever changing landscape of Bucks County, New Jersey and the Delaware River is well worth the effort.
