The newest State Monument tells the fascinating story of more than three centuries of trade and commerce that traversed the trail, linking Spain, Mexico, and the United States at a time when mules, trains, and horses were the only means of land travel. The award-winning building is set amidst the pristine Chihuahuan Desert north of the Jornada del Muerto and houses an exhibit that takes visitors on a virtual journey along the historic trail from Zacatecas, Mexico to Santa Fe, New Mexico. Visitors can discover the indigenous people encountered by the Spanish and the impact the arrival of the Spanish had on the formation of New Mexico. Remnants of the early journey remain today in hand-hewn carts, tools, leather water jugs, and religious altars and objects that accompanied the travelers into the northern territory. Visitors experience the journeys of Native Americans, Spaniards, and Mexicans; the military fort period; and the first Anglo settlers from the Eastern United States, through first-person stories and the art and objects they brought with them.

Central Insurance started out in 1876 as a fire insurance company. The threat of a disastrous fire was always very real and the equipment used to fight fire primitive. F. W. "Bill" Purmort, Jr., President of Central from 1964 to 1994, first took an interest in collecting fire equipment in 1969. He gradually built Central's museum into one of the finest privately owned collections in the U.S. The museum exhibits a collection of leather fire buckets dating back to the 1700s; over 600 antique fire toys consisting of cast-iron, rubber, glass, tin, and wood construction; a large display of fire extinguishers and glass fire "grenades" dating from the 1850s; a rare and valuable collection of "firemarks" dating back to 1720; a wardrobe of antique fireman helmets and uniforms; Van Wert's first hand-drawn pumper used in 1871; an Ahrens horse-drawn steam pumper which was purchased new in 1907 by the city of Van Wert and restored by Central; and a 1926 Ahrens-Fox pumper, the Rolls Royce of firetrucks.
