A small Jewish community lived in Puente Castro until the twelfth century. It disappeared during the wars between Castile and León.

The cemetery has yielded more than a dozen magnificent tombstones. Three of them have been on permanent loan at Toledo’s Sephardic Museum since 1969, and a fourth can be seen at the diocesan museum in León. A fifth one, at the Archaeological Museum of León (Museo Arceologico de León), was discovered in fragments in 1983 and probably dates from 1100. Its elegantly written inscription reads: “Cientos the Saint may be blessed and absolved; take him in Your mercy and resurrect him to the life of the future world, amen.”
