El Bayo is a settlement in the municipality of Ejea de los Caballeros, in the province of Zaragoza.

[1] Along with other settler villages of Ejea de los Caballeros, this locality was inaugurated on April 8, 1959, and quickly the first settlers began to arrive, coming from Ejea, Biota, Carenas, Nuévalos, Farasdués, Gallur, Rivas, Uncastillo and Tiermas, among others.

The village took its name from the medieval settlement that had existed in the same place from 1100 until 1380, when it was razed due to the clashes between Aragon and Navarre.

These remains, together with three other medieval buildings and a necropolis from the same period, form the ruins known as Las Torres de El Bayo.

On May 10, the festivities in honor of Isidore the Laborer are celebrated, along with the other settler towns due to their main source of income from agriculture.
