Duane's take
The official marker at San Elizario Chapel tells it this way, and here's my telling of it. Now, most chapels have a straightforward story. This one has been moving, flooding, and rebuilding for centuries, and it is still standing to prove it.
The chapel's full name is Capilla de San Elzeario, and it takes that name from St. Elzear, a thirteenth-century French patron of the military. So right away you've got a French saint watching over a Spanish garrison in what would become Texas.
History has a sense of humor. The military post it was attached to went by a few names over the years, Presidio de San Elzeario, also written Elceario, and later Elizario, but it was one and the same place. That presidio was originally situated about thirty-seven miles to the southeast of where you're standing now.
In 1789, the whole operation was picked up and moved to this very site. The chapel came with it, naturally. But the Rio Grande had its own opinions about the original chapel's future.
Floods came and did what floods do, and the original structure was damaged beyond saving. So the people here built anew. And here is the part worth listening to.
They didn't just haul in fresh materials and start from scratch. They made new adobe bricks, yes, but they also pulled bricks from the walls of the original presidio itself and built the present chapel out of those. The old fort became the house of worship.
What had been military became sacred, in brick and in memory. What stands here today is considered a fine example of the Spanish Colonial Revival style, and more than that, it is described as a tangible reminder of the Hispanic and Catholic heritage of this region. A saint from thirteenth-century France, a Spanish garrison that moved thirty-seven miles, a river that had other plans, and bricks that refused to be forgotten.
That is the Capilla de San Elzeario.
What the marker says
(Capilla de San Elzeario) Named for the 13th-century French patron of the military, St. Elzear, Capilla de San Elzeario was established as part of the Spanish military garrison of Presidio de San Elzeario (also Elceario, later Elizario) when it was moved to this site in 1789 from its original location 37 miles to the southeast. After Rio Grande floods damaged the original chapel, the present chapel was built with new adobe bricks and bricks from the original presidio walls. A fine example of the Spanish Colonial Revival style, it is a tangible reminder of the Hispanic and Catholic heritage of this region. Recorded Texas Historic Landmark - 1962
