With the help of Countess Mariana di Fusco, he inaugurated a confraternity of the Rosary and in October 1873 started restoring a dilapidated church.
He sponsored a festival in honor of Our Lady of the Rosary.

In 1875, Longo obtained as a gift a painting portraying Our Lady of the Rosary, with Saint Dominic and Saint Catherine of Siena.
Sister M. Concetta de Litala of the Monastery of the Rosary at Porta Medina had been holding it for the Dominican priest Alberto Radente.
Radente had acquired it from a junk-shop dealer in Naples for a very small sum.
The painting was in bad condition and Longo wrote of his immediate distaste of the poor artistic quality when he first saw it.
However, he accepted the gift to conserve funds and to not insult Sister Concetta.
Longo raised funds to restore the image and placed it in the church in an effort to encourage pilgrimages.

Alleged miracles began to be reported and people began flocking in droves to the church.
Longo was encouraged by the Bishop of Nola to begin the construction of a larger church—the cornerstone being laid on May 8, 1876.
The church was consecrated in May 1891 by Cardinal La Valletta (representing Pope Leo XIII).
In 1939, the church was enlarged to a basilica, known today as the Basilica of Our Lady of the Most Holy Rosary of Pompei.
