Bowman's Hill Tower
On top of Bowman's Hill, this 125-foot fieldstone tower provides a spectacular view that extends up to 14 miles, weather permitting, taking in the Delaware River and countryside. It was built in 1929–31 to mark what might have been a lookout point for Washington's army, but historians have found no evidence of this. You can walk up to the observation deck; an elevator (out of service at this writing; call ahead) will take you far enough that you have just 23 steps via a narrow circular staircase.
