Dubuque, United States

Iowa's oldest city on the Mississippi bluffs

Dubuque climbs the bluffs on the Mississippi's west bank where Iowa, Illinois and Wisconsin meet, with a riverfront port and Dubuque Regional Airport. A restored working district and river museum front the water.

Named for early lead miner Julien Dubuque, it became Iowa's first city and grew on lead, lumber and river trade. The Fenelon Place cable railway, built in 1882, still climbs the bluff.
