Mission Concepción

The compound tells its evolution in masonry: walls finished in 1745, judged insufficient, rebuilt in the early 1760s with living quarters built into them; a convento with a store room, porter’s lodge, library and refectory; a limestone quarry still visible beside the parking lot. Secularization began in 1794, when the mission’s lands were distributed to the thirty-eight Indians remaining.

The building then had a second, military career: a revolutionary headquarters in 1813, the site of the Battle of Concepción in October 1835 — Bowie and Fannin’s Texas rebels beat a larger Mexican force on the grounds — and an American supply depot in the Mexican-American War. The Catholic diocese resumed the buildings in 1855; WPA crews did the first large restoration in the 1930s; UNESCO listed it with the other San Antonio missions in 2015.

The mission was a working parish inside a chain of military posts; baptisms, marriages and burials ran in the register through the whole colonial period, even as raids and disease shrank the congregation. After the 1835 battle the church sheltered Texan wounded, and a decade later American quartermasters — the building housed both sides of both revolutions.

The mission’s most documented strangeness is painted: the church and convento were covered inside and out in geometric frescoes, and four rooms still show them. The library ceiling holds the famous “Eye of God” — a sunburst face — and conservators who cleaned it in 1988 found a second eye, a mustache and a goatee under two and a half centuries of grime and overpaint.

Father Juan Morfi inspected the missions in 1778 and left the record’s best line: “No one could have imagined that there were such good artists in so desolate a place.” The file notes that the artists were the mission Indians — trained to paint the theology onto the walls that housed them.

A 2010 preservation uncovered still more original plaster and pigment in the sanctuary and the baptistry at the bell-tower bases — the walls keep releasing evidence by the square foot.

The claims are quiet lore for a quiet building: a presence in the church and convento, footsteps where the tour isn’t standing — the gentlest reports in the San Antonio mission cluster, attached to nearly three centuries of continuous worship and to the converts whose names survive in the register’s margins.

The file’s verdict: the Eye of God on the convento ceiling watched everything the record describes — epidemics, siege, secularization, restoration. Whatever else reportedly watches the rooms has seniority only in the telling.

The active parish keeps the church’s oldest job — weekend Mass fills the nave beneath frescoes the congregation’s ancestors painted. Concepción’s file ends where it began: a church still doing its work, unrestored on purpose.
