Toledo, city in northwestern Ohio extending along both banks of the Maumee River where it empties into Lake Erie. Toledo is a major port of the Great Lakes and famed for its glass manufacturing. It is the seat of Lucas County.
The city grew in a region known as the Black Swamp, a vast, ancient lake bed on either side of the Maumee River. When drained in the late 19th century, the Black Swamp soils provided a fertile base for agriculture which helps support the Toledo area today. The city's mean elevation is 179 m (587 ft).
