Historia
1527 — Don Sebastián Gaboto, discoverer of the lands that are now the Exaltación de la Cruz Partido, baptizes the Paraná de las Palmas river as such on Palm Sunday that year, due to the existence of many palm trees on its banks which were used in that celebration. 1536 — Don Pedro de Mendoza founds the city of Buenos Airesfor the first time. 1580 — Don Juan de Garay, from Asunción of Paraguay, founds Buenos Aires for the second time to reaffirm the rights of the Spanish Crown against the Lusitanians' expansionist intentions. One of the measures used in implementing this territorial defense, on October 24 of this year, is the distribution of land and many small farms among 25 neighbors who had accompanied Garay in the final founding of Buenos Aires. The same year, near the second foundation of Buenos Aires, the fields of the partido are used to make up "Pago de la Cañada de la Cruz". 1614 — The Compañía de Jesús establishes itself on the lands of the present districts of Exaltación de la Cruz and Zárate, initiating livestock resource exploitation and control of goods from the north. In addition to a small farm, the Jesuits found a harbor and a school. 1730 — Don Francisco Casco de Mendoza, the first in his family to settle in these places, builds a chapel for private devotion in one of his fields along the Arroyo de la Cruz. It was located in the present yard and parsonage. 1735 — On September 14, the day the Catholic Church celebrates the feast of the Exaltation of the Cross, the ecclesiastical authority raises the Casco de Mendoza's chapel to viceparish status, opening it up for public worship in 1750. 1750–1760 — The town of Capilla del Señor is established around the viceparish, fulfilling the Real Pragmatic of King Charles III which mandated that "all inhabitants rurally dispersed should be near a religious centre so their children can be educated in Christianity and in the first few letters". 1772 — Casco sells the land surrounding the church, where the town of Capilla del Señor, the capital of Exaltación de la Cruz Partido, exists today. 1784 — The Illustrious Cabildo "Justice and Regiment" orders the creation of Cañada de la Cruz Partido, the former name of this area. The boundaries of this district would become those of the Capilla del Señor Parish. 1785 — On January 1, the district's own ruler is designated. The designation falls on Don Francisco Remigio Casco de Mendoza, grandson of the owner of the original oratory. 1854 — Zárate gets autonomy. 1855 — Campana gets autonomy. As a result of the creation of these new partidos, Exaltación de la Cruz becomes an interior territory of Buenos Aires Province, no longer collecting taxes on merchandise entering via Zárate and Campana harbors.
