Mission San Clemente is known as the first Spanish mission in Texas, although there were actually two different missions built on the same location, more than 50 years apart. The Spanish Franciscans visited the area for a short time in 1629, and promised the local Jumano Indians that they would return. In 1632, the friars built a mission located near the confluence of the Concho River and the Colorado River, which was then known as the Río San Clemente. The mission was constructed of logs, and operated for only 6 months; during that time, 2-3,000 Indians were baptized. In 1684, another mission was built near the same site by Juan Dominguez de Mendoza and Fray Nicolas Lopez. The lower floor of the log structure was a chapel, and the upper floor was an lookout post. The exact location is not known.
