Chiesa dell'Immacolata Concezione, Catholic church building in Portici, Italy

The Chiesa dell'Immacolata Concezione, known as the "Chiesa dei Ferrovieri", stands at via San Cristoforo 50 in the Cupa San Cristoforo area of Portici. It grew out of Villa Croce, a two-storey palazzotto with an inner courtyard and, behind it among orange trees, a mezzanine villa reached by a two-ramp staircase. The former Oratory of the Sacred Heart, consecrated in 1879, was restored from 1937 and reopened as a parish church in 1942.

The Ladies of the Sacred Heart bought Villa Croce in 1875 and opened a religious house; the first stone of the Oratory of the Sacred Heart was laid on 15 December 1876, not a first service. The church was consecrated on 16 September 1879. After the 1906 Vesuvius eruption the institute was abandoned, and in 1942 Cardinal Alessio Ascalesi erected the parish of Maria SS. Immacolata.

This church serves as a spiritual center for the local Catholic community, hosting regular masses and religious celebrations throughout the year. It functions as a gathering place where residents come together for worship and important life ceremonies.

The church stands at Via San Cristoforo 50, in the Cupa San Cristoforo area on the outskirts of Portici. It is still an active parish, so the interior is best seen outside mass times; the building itself can be viewed from the street at any hour.

The church is also called "Chiesa dei Ferrovieri" because the State Railways bought the former convent in 1916 to house workers' families and offered the oratory to the Naples Curia in exchange for the demolished Pietrarsa church. The parish was erected on 7 March 1942 by Cardinal Alessio Ascalesi, and its title of Immaculate Conception continues the devotion of the Pietrarsa chapel.
