Platteville is the largest city in Grant County in southwestern Wisconsin. The population was 11,224 at the 2010 census, growing 12% since the 2000 Census. Much of this growth is likely due to the enrollment increase of the University of Wisconsin–Platteville. It is the principal city of the Platteville Micropolitan Statistical area, which has an estimated population of 49,681. Platteville is located atop the greater Little Platte River valley, in the Southern Driftless Region of Wisconsin.
Platteville was settled by Pioneers and early Lead Miners along inlets and flat groves of The Rountree Branch and Little Platte River. Part of the greater Upper Mississippi River system. In the Driftless Region of Southwest, Wisconsin.
This is evident in the community as different areas of town are carved by ridges, narrow valleys, and steep hills. It can also be seen in the irregularity of the streets in the community. As the town grew, roads were given odd routes, to avoid the steep ravines and mining shafts strewn about the locality. 
The town of Platteville was officially established in the 1820’s as a flourishing mining community. This is in part due to its close proximity to Dubuque, IA & Galena, IL. Both were thriving cities along the Mississippi River trade route. And also, because of the rising demand for lead throughout the United States from the 1820’s-1850’s.
Platteville was officially founded in 1829 by John H. Rountree. A southern businessman who had moved to the region prior, in hopes of finding wealth during its lead rush.
John H. Rountree as well as other wealthy southerners in the area, like former Wisconsin Governor Henry Dodge, brought slaves with them during the lead rush. They also brought freed black laborers, with intentions for them to work the mines at a more affordable cost, often nothing. This was illegal, even at the time. Yet, was a practiced in the region until after the Civil War. 
A family of freed African-Americans from the region later settled a community known as Pleasant Ridge, Grant County, Wisconsin just west of Platteville. This served as a safe haven for many coming up from Arkansas, Tennessee, and Mississippi. Some staying and raising families but most continuing on their way in hopes of finding success elsewhere. 
By the 1849s lead ore production was decreasing. However, the mining of zinc ore quickly filled the void for prospective work. Platteville had become an established town, complete with schools, a private preparatory academy, newspaper, several churches, and a telegraph service as of November 1849.
During this time, both a teachers' college and a mining college were founded. The Normal School was established on October 9, 1866 to train teachers for elementary school grades. The Wisconsin Mining Trade School opened in January 1908.
In 1959, these two colleges were merged to become Wisconsin State College and Institute of Technology. Its curriculum was developed to add graduate programs and departments, particularly in engineering. In 1971 it was renamed as University of Wisconsin–Platteville, to reflect its expanded programs in graduate study. Other additions included criminal justice and, in the early 21st century, UW Platteville is also considered to have the best criminal justice college in the Midwest.
From 1984 until 2001 the Chicago Bears football team held summer training camp on the campus of University of Wisconsin–Platteville. Their program resulted in a substantial infusion of money into the local economy each summer. The town felt the decline after the Bears moved their training camp to Olivet Nazarene University in Illinois.
In 2004, the University of Wisconsin System gave its approval to the University of Wisconsin–Platteville's plan to expand the student enrollment from 5,000 to 7,500.
In 2004, U.S. Highway 151 was upgraded to a limited-access highway; it bypassed the city south of Platteville. Prior to the upgrade, the highway exits were closer to Platteville. The city made changes to adjust to the new southern US 151 bypass, and it has influenced subsequent development. A new hospital was built just north of US 151 and next to its off ramps. A Walmart Supercenter and a Menards have opened near the northern end of the US 151 bypass.
Platteville is a college town, with a population and economy strongly influenced by the university. It has had some development in the white-collar sector. That growth is a result of the increasing number of engineering firms locating in Platteville to take advantage of being associated with UW-P's engineering program. More recently there has been development in the blue-collar sector as well due to the increased construction activity throughout the community.
Platteville is located at(42.73707, -90.477501). It is in the Hollow Region, as named by early southern miners, in the rolling hills of southwestern Wisconsin.
According to the United States Census Bureau, the city has a total area of 5.45 square miles (14.12 km2), all of it land.
Platteville is serviced by Wisconsin State Highways 80 and 81, as well as U.S. Highway 151. Originally, U.S. 151 went through the valley that made up the southern border of the city limits, but with the completion of the four-lane limited-access superhighway, traffic has been rerouted and now loops south of the city.
The minerals in the area consist of galena, a sulfide of lead (lead 86.6, sulfur 13.4). Sphalerite or zinc sulfide is also, common in the region. Zinc and lead mining were in heavy production through the 1820s – 1920s. Consequently, there are few straight streets in Platteville. As a result of the mining in the 1800s leaving a honeycomb of abandoned old mines, streets were located to avoid the mines.

Aside from Platteville Municipal Airport (KPVB), which serves the city and surrounding communities for general aviation, Platteville has minimal commercial air access. The closest airport with any regularly-scheduled commercial service is Dubuque Regional Airport, and the closest airport with regularly-scheduled commercial international flights is Chicago O'Hare International Airport.
Platteville's primary road access is via U.S. Route 151, which acts as an expressway for the region; US 151 has three exits near the city center. Wisconsin state routes 80 and 81 also serve Platteville, cutting through the central business district as sort of a "main street".
Platteville Public Transportation provides the community with bus service and paratransit service.
Platteville no longer has railroad service. It was previously served by the Chicago & Northwestern Railroad (C&NW) via an 8-mile branch off the Montfort Junction to Galena line at Ipswich. The line entered Platteville from the east-southeast and curved around to the north. The line then joined the Chicago, Milwaukee, St. Paul and Pacific (Milwaukee Road). This in effect created a large 180° curve in the southeastern part of Platteville where the mines, depots and other rail-dependent industries were located. The Milwaukee Road branch continued on to the ENE then east for 17 miles where it branched off another Milwaukee Road branch line to Mineral Point at the town of Calamine. Passenger service ended on the C&NW in 1951 and was replaced by mixed train service on the Milwaukee Road in 1952. Freight service continued on the Milwaukee Road until 1974 when the line was abandoned and pulled up. It left the C&NW moving only a few cars per week which applied to abandon the route. The abandonment was granted in 1980 and the line was pulled up forever ending railroad service to Platteville.
The Platteville School District serves the Platteville area. Platteville High School is the area's public high school. Platteville High School's mascot is "Henry Hillmen". The University of Wisconsin–Platteville is located in Platteville.
The main source of culture in Platteville is the Center for the Arts on University of Wisconsin–Platteville campus, which sponsors a steady stream of well-attended professional touring events.
At the museums one can tour Lorenzo Bevan's 1845 lead mine, ride a 1931 zinc mine train, and view many exhibits on Platteville's mining history as well as Rollo Jamison's personal collection of artifacts.
Built in 1837 by the Rev. Samuel Mitchell, this home still contains many of the original furnishings. The home was a home of the Major John Rountree, one of Platteville's founders. The walls are two feet thick and made of dolomite Galena limestone.
Main article: Platte Mound M
The M is a monogram for the former Wisconsin Mining School (now the University of Wisconsin–Platteville).
The first M was first constructed in 1936 when two men, Raymond Medley and Alvin Knoerr climbed the Platte Mound and trudged through 2 feet of snow to form a huge letter M. Actual construction of the stone M began in the spring of 1937 and was completed in the fall of the same year.
The M is composed of rocks laid on Platte Mound and is whitewashed every year. The M is 241-feet tall, 214-feet wide and legs that are 25-feet wide.
The M can be seen many places in Platteville and sometimes in Iowa, on a clear day. Atop the Platte Mound and the M viewers can see three states: Wisconsin, Iowa, and Illinois.
The M is lit once a year during the University of Wisconsin – Platteville college homecoming.
