Warrenton is an unincorporated community in northeastern Fayette County, Texas, United States. Located on State Highway 237 between Spencer Pool and Coon Creek, twelve miles northeast of La Grange. Founded by William Neese, who landed in Galveston in 1847 and named the new settlement that grew around his store for Warren Ligon, another early colonist. This area was settled by many German colonists who, with an admixture of Anglos, formed several small farming communities based on the production of cotton, corn, and dairy products. The community flourished in the late 1800s. A post office was established in 1873, when the town had a population of over 100, churches, schools, a gin, and supporting businesses. Poor soil conditions led to a shift to cattle and poultry after 1900. By 1950, the number of businesses in Warrenton had declined to seven, and the population held at 180. By 1985, the population was down to fifty, but twelve antique stores had opened and St. Martin's Church, at twelve by sixteen feet proclaimed the world's smallest Catholic church, attract visitors.
