Perry County at a glance: towns and land
The county seat is Perryville; Altenburg, Frohna, and Longtown are among the other communities you can zoom to. The county dates to 1820, named for Oliver Hazard Perry, and older deeds may still refer to landmarks from that era. By Census Bureau figures, the county had roughly 18,950 residents in 2023, spread over about 474 square miles of land. Outside Altenburg the parcels open up quickly into farms, timber and small acreage homesites. Parcels touching the Capes on the Mississippi River tend to run long and narrow back from the water, a pattern you can see clearly on the Perry County map. Public ground such as Middle Mississippi River National Wildlife Refuge appears as large unbroken blocks, and the private parcels around it draw hunters and recreation buyers.
