Lockport: “Lock City”
Lockport was a key terminus along the Erie Canal. One of the great hurdles in creating the canal was found here in the Niagara Escarpment, a wall of limestone which needed to be overcome. Since no single lock could handle this, a series of five locks, one on top of each other, was built to get boats up and over the escarpment and on their way to Buffalo. This “Flight of Five” was the greatest engineering marvel of the Erie Canal and still attracts thousands of visitors to the “Lock City” annually.
