In 1824, as the importance of the clock industry grew, Plymouth's business center moved to Terryville named after Eli Terry Jr. As the lock industry grew in the 1830's, Terryville, became known as "America's Lock Capital" because 100 million locks were made here. To learn about the rise of the lock industry, visit the Lock Museum of America that has 8 rooms displaying the nation's most extensive collection of locks, keys, Victorian hardware, and locksmith related items. Of special interest is the Eagle Lock Company Room containing 1,000 plus locks and keys manufactured from 1854 to 1954; the Bank Lock Room with a selection of bank, vault, safe, and time locks; the Corbin-Russwin Room with a large display of ornate hardware, the Antique Lock Room with a large display of colonial locks and Ornate European Locks dating to the 1500's and the Yale Room with a display of locks made by that company from 1860 to 1950.
Just beyond the Lock Museum, on your left, you will pass the Eli Terry, Jr. Water Wheel that supplied early clock and lock companies with power. This is the only existing manufacturing water wheel in the U.S. with original gear.
