Situated in the Southwestern part of Wisconsin, Lafayette County lies within the unglaciated area of the state in
the driftless region bordering the State of Illinois. With an area of 643 square miles or 411,520 acres, it has a
population of 16,263 according to the 2002 final estimate.
The first settlements perfected by permanent occupation in Lafayette County were made during the year 1824 and were
due to the existence of the lead mines, which led to early development and stability of the County. Lafayette County
was formed in 1847 when the Legislature divided Iowa County into two separate counties. The Southern portion became
Lafayette County, named after Marquis de Lafayette, hero of the Revolutionary War. Today, Lafayette County is one of
the leading agricultural counties in the state, with 1,400 farms averaging 285 acres in size. Agriculture is the
leading enterprise of the County.
"LAFAYETTE, County, is bounded on the north by Iowa, on the east by Green, on the south by the State line, and west by Grant, and is 21 miles north and south, by 30 miles east and west. it was organized February 4, 1847. The county seat has been a vexed question since the organization, but it has finally become established at the village of Shullsburg, a few miles southwest of the geographical centre. This county is more celebrated for its mining operations than for its agricultural products, simply, however, because the former has been prosecuted to the neglect of the latter. The Peckatonnica and Fevre rivers are the principal streams. The population in 1847 was 9,335; 1850, 11,556. Dwellings, 2,079; farms, 399; manufactories, 21."
Lafayette is in the mineral region of Wisconsin and its products are those of the mines. A very large proportion
of the lead sent from this State is raised in Lafayette. Though the lands are rich, yet attention has so far been
attracted to its minerals, that its agricultural products have been but a small part of its riches. Under the past
system of prospecting for lead and copper, the uncertainty attending this branch of industry has turned the
attention of the miners to agriculture, and Lafayette will undoubtedly soon show a more rapid increase of wealth and
of stable prosperity than has ever attended mineral research. The land is good and mostly occupied. It lies in the
Mineral Point land district.
The Mineral Point and the Southern Wisconsin Rail Roads pass through this County.--Shullsburg is the County Seat.
As reported by the Census Bureau, the county has a total area of 635 square miles (1,644 km2), of which, 634 square miles (1,641 km2) of it is land and 1 square miles (3 km2) of it (0.16%) is water.
