Its construction was ordered by the Knight Commander and Preceptor General of the Order of San Antonio, Damián García Olloqui,^[7] for the San Antón Convent in the town, and transferred to the Church of San Juan when the Order of San Antonio was canonically attached to the Order of Malta in 1777 and finally became defunct in 1791.

Ruins of the San Antón convent

Just outside, Castrojeriz on what was formerly the palace and the garden of King Pedro I of Castile, are the ruins of the ancient monastery of San Antón, run by the Hospital Brothers of St. Anthony, who were dedicated to caring for the sick who came along the Camino de Santiago, especially those with the disease called St. Anthony's fire, sacred fire, fire of sick. Currently only the arch that formed a tunnel, through which pilgrims came and went, is left standing.

This monastery was under royal protection, that is why there are royal crests on the front of the church and on the keys of the vaults. It was founded by Alfonso VII in the twelfth century (1146), and was known as the royal xenodoquio of San Antonio Abad.^[8] The present ruins are from the fourteenth century. The hospital was very important, because it was the headquarters of the General Commandery of the Order of San Antonio in the various realms of the Crown of Castile and Portugal, with over twenty dependent encomiendas (house-monastery-hospital). The ceremonies that the Anthonian monks held to bless various objects were famous, to which many adherences came. The symbol of the Order was the tau cross.
