The National Register of Historic Places is the official list of the Nation’s historic places worthy of preservation.

Wyoming was the location of the world's first commercial oil well, which was drilled in 1859 near present-day Casper.
Weston County, Wyoming, located in the northeastern corner of the state, has a rich history shaped by Native American tribes, early explorers, the expansion of the railroad, and the growth of the coal mining industry.

The area that would become Weston County was originally inhabited by various Native American tribes, including the Lakota Sioux and Cheyenne. These tribes relied on the abundant wildlife and natural resources in the area for their survival. However, the arrival of European explorers in the early 19th century, such as the Lewis and Clark expedition, brought significant change.

With the completion of the Transcontinental Railroad in the late 1860s, Weston County experienced a wave of settlement, as the railroad became a major route for immigrants heading west. The town of Newcastle was established in 1888 as a result of the railroad's expansion, becoming the county seat of Weston County. The railroad brought economic development and allowed for the transportation of goods and resources, stimulating growth in the region.

One significant industry that emerged in Weston County was coal mining. In the late 19th and early 20th centuries, extensive coal deposits were discovered in the region, leading to the establishment of numerous coal mines. The demand for coal increased as it became essential for fueling locomotives and powering industries. The mining industry boomed, attracting workers and investment to the area. Coal mining remained a vital part of Weston County's economy for many years.

Today, Weston County continues to thrive, with a diverse economy including agriculture, energy production, and tourism. The area's vast natural beauty, including the Black Hills National Forest and Devils Tower National Monument, attracts visitors from around the world. The legacy of Weston County's history can still be felt in its historic towns, cultural heritage, and the resilience of its residents who have adapted to changing times while preserving their heritage.
