Two Miles Southwest to Fort Belknap
Newcastle, TX
Established in 1850, Fort Belknap became the largest military post in northern Texas, anchoring the line of frontier defense against raids on the settlements. It served as the first county seat of Young County and, from 1858 to 1861, as a station on the Southern Overland Mail linking St. Louis to San Francisco. This marker points travelers two miles southwest to its site.
