History of Irion County

Many years ago, from 1858 to 1861, the Butterfield Overland Mail route passed through this area. This was a famous stagecoach service that carried mail and passengers across the country.

In 1876, John Arden brought the first group of sheep to the county. Around the same time, Billy Childress started the Longhorn 7D Ranch.

The Texas Legislature officially created Irion County in 1889. It was formed from parts of Tom Green County. The first county seat was a town called Sherwood.

An important discovery happened in 1928 when oil was found in Irion County. This helped the county grow. Later, in 1936, Mertzon became the new county seat.

Today, the Old Irion County Courthouse in Sherwood is a special historical building. It is the only place in the county listed on the National Register of Historic Places. This means it is recognized as an important historical site.
