Engle’s Mammoth Pennsylvania Clock, a one-of-a-kind, touted to be the 8th Wonder of the World is now reported to be on exhibit at the National Watch and Clock Museum in Columbia, PA.  Historical Image documenting the  one-of-a-kind clock in early America.


The first known monumental clock made in the United States was the Engle Monumental Clock. The clock was made entirely by clock designer Stephen Decatur Engle in Hazleton, Pennsylvania. It took Engle 20 years to complete the construction of this clock which was finished in 1878. Wanting to display the clock rather than turning a profit, he turned the clock over to two Philadelphia entrepreneurs who marketed the clock as "The Eighth Wonder of the World." They toured the clock throughout the Eastern United States, charging 15–25 cents to view it. It continued to tour across the Eastern United States for 70 years before disappearing in 1951.

The clock is currently at the National Clock and Watch Museum. America.
