Construction.
In planning documents, the monument was consistently described as respectfully a foot or two shorter than the 555-foot-tall Washington Monument, and from the floor of the museum to the top of the star, it is. Upon completion, however, measurements included the 15-foot-high stepped entrance pedestal between the ground and the floor of the museum -- making it approximately 570 feet, and taller than the Washington Monument . | Source: San Jacinto Museum
