Rosenberg is in central Fort Bend County southwest of Houston. The area was originally settled by Stephen F. Austin's Old Three Hundred around 1823. When the railroad bypassed Richmond and built west of that city, it established a station at the junction of the Gulf, Colorado and Santa Fe and the Galveston, Harrisburg and San Antonio railroads. Rosenberg was named for Henry Rosenberg, president of the Gulf, Colorado and Santa Fe Railway in 1883. In the 1920s oil was discovered in Fort Bend County and the city became a boomtown.
The Rosenberg's historic downtown district offers an abundance of shopping opportunities, including antique shop and an old-fashioned soda fountain shop. The antique district is home to the Rosenberg Railroad Museum, a replica of Rosenberg's original Union Depot. Rosenberg's economy is based upon a strong mineral petroleum industry, as well as agribusiness.
