One of the best remaining examples of a frontier military post, Fort Davis was established in 1854, named after then-secretary of war Jefferson Davis. Surrounded by geological formations that offered natural defense as well as beauty, the fort was first occupied by six companies of the Eighth U.S. Infantry to battle hostile Comanches, Kiowas, and Apaches. Confederate soldiers controlled the fort for a spell in 1861; afterward, the fort sat vacant until 1867. It rose again as a stronghold in the Indian wars of the late 19th century, pitting the African-American 10th U.S. Cavalry and other soldiers against the Apaches, until it was abandoned once and for all in 1891. Ten structures have since been restored, five of which are furnished with period antiques. Most Texas forts are either run-down or sitting in the middle of a barren plain, so this one -- well manicured with a stunning rocky backdrop -- is a standout. Expect to spend a little more than an hour if you tour all 10 structures.
