Quincy, Massachusetts: World's Most Nearly Perfect Sphere

Made of granite, weighs almost 10 tons. It's been moved, repolished, and exposed to Massachusetts weather for over 80 years. It must be less nearly perfect by now, but we couldn't see it.

World's Most Nearly Perfect Sphere

Quincy Granite Ball Monument, a polished granite sphere six feet in diameter and weighing 9.5 tons.

Donated in 1925 by the Granite Manufacturers' Association of Quincy to commemorate the 300th anniversary of the city's settlement. The ball appeared in Ripley's Believe It or Not as the "most nearly perfect sphere in the world."

It stood next to city hall for 12 years. In 1937 it was moved to the traffic rotary at Fore River Bridge. In 2006 it was repolished and moved back next to the city hall.
