San Miguel Arcángel de Oposura, a large burnt brick church with vaulted ceiling, side bays, and an octagonal chapel with a wooden roof, was built by unidentified maestros brought to the site at great expense by Father Daniel Janusque sometime before his death in 1724. It continued under two of his successors until it was finished in February 1738.
The town was renamed Moctezuma in 1828, while before the name had been San Miguel Arcángel de Oposura, and later “Oposura”. Etymologically, Oposura means place of a lot of ironwood.
