The Miami & Erie Canal was built between 1825 and 1845, an engineering marvel stretching from Cincinnati to Toledo. This canal was heavily used until competition from the railroad caused the decline of the canal system. The Miami & Erie Canal was last used commercially in 1929. Today, the Miami & Erie Canal Trail spans nearly 40-miles from Delphos to Fort Loramie, passing through many quaint western Ohio towns and villages. Numerous locks, spillways, and historic buildings remain from the canal.
