History The city was founded by Spanish conquistador Pedro Carrillo Davila in 1569, as a fortification or military garrison to protect travelers against the Chichimecas warriors. The fortification of Ojuelos was one of the seven ones built at the request of the Viceroy Martín Enriquez de Almanza in the important route Mexico-Zacatecas which later became the Camino Real de Tierra Adentro. The fortification in Ojuelos was the first being built and it is only one still in place. The decision to build the seven fortifications was made by Viceroy Enriquez de Almanza in response to deadly attacks made by Chichimecas commanded by their legendary leader Maxorro. Ojuelos has a significant value in Colonial history in Mexico and North America, since its fortification is the only one which has survived to present day keeping its main structure as originally built in 1569. Currently, it houses the offices of the City Hall and a Library. In 1874, Ojuelos was designated as Municipality by Ignacio L. Vallarta, Governor of the State of Jalisco, after a long border dispute with the state of Zacatecas.
