On 4 March 2019, Pope Francis raised it to a metropolitan archdiocese, with three suffragan dioceses within its ecclesiastical province. The suffragan dioceses are Merlo-Moreno, Nueve de Julio, and Zárate-Campana. The first had been in the Buenos Aires province, and the other two were in the La Plata province. Francis also appointed the first metropolitan archbishop, Jorge Eduardo Scheinig, who had been titular bishop of Ita.[1]
