Rolla // is a city and county seat of Phelps County, Missouri, United States. The population in the 2010 United States Census was 19,559. Rolla is located approximately midway between St. Louis and Springfield along I-44.
It is the home of the Missouri University of Science and Technology, well known, both nationally and internationally, for its many engineering departments and computer science department.
The headquarters of the Mark Twain National Forest is located in Rolla. In addition, this is part of the Ozark Highlands American Viticultural Area, with vineyards established first by Italian immigrants to the area.
The first European-American settlers in Phelps County arrived in the early 19th century, working as farmers and iron workers along the local rivers, such as the Meramec, the Gasconade, and the Little Piney. In 1844, John Webber built the first house in what became the City of Rolla. Nine years later, railroad contractor Edmund Ward Bishop, considered to be the founder of Rolla, settled in the area. The state officially established Rolla as a town in 1858.
Two stories account for how Rolla was named. One story, widely regarded as a folk legend, and acknowledged as such by the Phelps County Historical Society, arises from the competition between Rolla and neighboring Dillon, Missouri, to be designated the county seat. When Rolla was made the county seat in 1861, the residents of Dillon, having lost a round, were allowed to choose the name of the new city and named it Rolla, after a good-for-nothing hunting dog.
The more widely accepted story came from a citizens' meeting about naming the town. Webber was said to prefer the name Hardscrabble (which was used to describe the soils in the region) and Bishop pushed for the name Phelps Center. New settlers from North Carolina voted to name the community after Raleigh their hometown but chose to spell the Missouri version phonetically.
With numerous settlers from the South, many residents of Rolla leaned toward the Confederacy during the American Civil War and the town was taken by Union forces in June 1861. They built two minor forts — Fort Wyman and Fort Dette — during their occupation.
For most of its history, Rolla has served as a transportation and trading center. It was the original terminus of the St. Louis-San Francisco Railway, colloquially known as the "Frisco Line". Today, the BNSF Railway directly runs through the town.
Rolla was also a regular stop along U.S. Route 66, as it is almost located exactly halfway between the larger cities of St. Louis and Springfield. Today, Interstate 44, U.S. Route 63, and Route 72 all run through Rolla.
Rolla is located at  According to the United States Census Bureau, the city has a total area of 11.85 square miles (30.69 km2), of which, 11.83 square miles (30.64 km2) is land and 0.02 square miles (0.05 km2) is water. Running through the city is the divide line that separates the vast Missouri watershed (via the Little Piney and the Gasconade) from the substantially smaller Meremec watershed (via the Bourbeuse)..
