In a recent post about the Santa Fe plaza, I included a set of maps. If you look closely, you’ll notice that even the oldest of them identifies a small building on the south side of the square as the “military chapel.”
More properly called the Military Chapel of Our Lady of Light, and commonly referred to as La Castrense, this building was centered in the buildings on the south side of the Plaza and faced the Governor’s Palace on the north. The word Castrense means “belonging to the military profession,” so its nickname was appropriate, because the little church was built specifically for use by the members of the Santa Fe garrison.
The original chapel was completed in 1717 and then rebuilt and rededicated in 1761. The reconstruction was funded by Governor Francisco Antonio Marin del Valle and his wife, Dona Maria Ignacia Martinez de Ugarte. This power couple also donated a new altar piece, or reredo, which was carved from large pieces of limestone quarried north of Santa Fe near Pojoaque. Said to be the largest and most ambitious piece of artistic work ever attempted in New Mexico to that point, the piece filled the entire altar end of the building.
The chapel received further decorations around 1813, when Pedro Bautista Pino, New Mexico’s representative to the Spanish Cadiz, returned from Europe with two marble bas-reliefs which were mounted on the outside wall above the door from the plaza. Colonel Francisco Perea remembered years later that one of them represented “Santa Gertrudes wrapped in the coils of a large serpent, while the other, I believe, represented the mother of Jesus, Nuestra Senora de la Luz (Our Lady of Light), recuing a human being from Satan.”
The military troops stationed in Santa Fe attended services in the chapel monthly as well as on special occasions. During Governor Manuel Armijo’s first two administrations, he and the full garrison attended regularly, with the officers in full uniform. However, it seems unlikely that they continued to do so during his third term (July 1845 to August 1846) as the roof had fallen in. At least, that’s what Lt. James W. Abert reported in early October 1846. He also said the building contained “some handsome carved work behind the altar,” and that at least one of the bas-reliefs still remained over the door, the one that showed Our Lady of Light.
Abert had entered Santa Fe in the Fall of 1846 with the occupying U.S. army. Five and a half years later, in Spring 1851, newly appointed Chief Justice Grafton Baker, needed a place to hold his court and decided to use La Castrense.
The building, apparently repaired by this time, was set up with the necessary furniture and the grand jury was called. Unfortunately for Judge Baker, the grand jury members included Santa Fe native and former Mexican soldier, Donaciano Vigil. Vigil and his wife had been married in the chapel, and his father and an infant son were buried there. As former provisional governor under the U.S. rule, he had enough political clout to risk protesting the use of the chapel for civil purposes and enough connections in the city to rally public opinion behind him.
Baker threatened to hold court anyway and to have Vigil arrested, but when a crowd began to assemble outside and the commanding officer of the American troops rallied behind Vigil, the Judge gave way. He ordered the court moved across the plaza to the Governor’s palace. The men responsible for shifting the furniture didn’t have to actually remove it from the building. The crowd had already dumped most of it in the plaza.
The building doesn’t seem to have been immediately converted back to being a chapel. According to the 1891 Silver City Enterprise, in the 1850s, it was instead used to store captured cannons, including the Lone Star of Texas which had come into New Mexico in 1841 with the ill-fated Texas Santa Fe Expedition.
The guns must not have stayed there for long, because in 1859 Bishop Lamy exchanged the building for $2000 and land in the vicinity of the Parish church. The money went to repairs for church and the land became the site of St. Michael’s College and the Loreto Chapel.
La Castrense itself was demolished by its new owner, but not until the altar piece was preserved and carefully removed. It is now in El Cristo Rey, which offers a brochure about the reredos on its website. It’s nice to know that, even though the building itself had to give way to “progress,” at least some of its contents were preserved and still survive.
