Round Rock
Permanent settlement began in this area in the late 1830s. By 1848, former Austin Mayor Jacob Harrell moved here, selling town lots near the Stagecoach Road crossing at Brushy Creek. A post office named “Brushy Creek” opened in 1851 in Thomas Oatts’ store. Three years later, the name changed to “Round Rock” for a distinctive limestone formation marking a natural ford for wagons. With immigration from several states and Sweden, the population doubled during the 1850s, bringing new stores, churches, fraternal lodges and grain mills. The first institution of higher learning, Round Rock Academy, began in 1862. After the Civil War, the former trail and stage road became a prominent cattle drive route.
In 1876, the International-Great Northern Railroad developed a new townsite east of the existing Round Rock. A commercial district sprang up along Georgetown Avenue (Main Street) with construction of many limestone buildings. “New Town” quickly eclipsed the established settlement, whose postal name changed again to “Old Round Rock.” For months, the new site was the railroad terminus, bringing lumber and flour mills, cotton gins, blacksmith and wagon shops, banks, hotels, restaurants, stores and schools. Round Rock challenged the state capital for economic control of central Texas, boasting six hotels to Austin’s five and serving as the retail hub for several counties to the west. The railroad also made Round Rock a more cosmopolitan place, bringing new residents from all over the U.S. And all around the world. Well-positioned for growth by its location on major transportation routes, Round Rock became one of the nation’s fastest-growing cities by the late 20th century. Two dozen commercial buildings in Round Rock’s historic downtown were listed in the National Register of Historic Places in 1983
As one of the most visible programs of the Texas Historical Commission (THC), historical markers commemorate diverse topics in Texas history, including: the history and architecture of houses, commercial and public buildings, religious congregations, and military sites; events that changed the course of local and state history; and individuals who have made lasting contributions to the state, community organizations, and businesses.
The first oil well in the United States was drilled in Texas in 1859. The discovery of oil transformed the economy of the state and helped to make Texas one of the wealthiest states in the nation.
The region was first settled by European pioneers in the mid-19th century. The establishment of Fort Tumlinson in 1839 provided protection to settlers, and the population grew steadily with the arrival of more immigrants in search of new opportunities. In 1848, the county was officially organized and named after Robert McAlpin Williamson, a judge and soldier in the Republic of Texas.
During the Civil War, Williamson County faced significant challenges. Many residents joined the Confederate Army, and the county became a hotbed of conflict due to its location on the frontier between Union and Confederate territories. After the war, the area was able to rebuild and experienced a period of economic growth, driven by agriculture, cattle ranching, and the emergence of small towns and rural communities.
In the 20th century, Williamson County continued to develop and adapt to changing times. The discovery of oil in the early 1900s brought economic prosperity to the region, and the county experienced a boom in population and infrastructure. Today, Williamson County is a thriving part of the greater Austin metropolitan area, known for its strong economy, vibrant communities, and commitment to preserving its historical roots.
