Santa Monica, Modern church building in Rome, Italy

Santa Monica is a Catholic parish church in Lido di Ostia, Rome, built 1968–72 to a design by Ernesto Vichi. It has a Latin-cross plan with reinforced-concrete load-bearing elements, and the crossing is marked by the intersection of the four main beams carrying the ceiling. Outside, a portico runs alongside the facade and links the church to the other buildings of the parish complex.

Construction began on 13 June 1968, Corpus Domini, when Pope Paul VI blessed the laying of the first stone; the architect was Ernesto Vichi. The church was inaugurated on the evening of 7 December 1972 by Remigio Ragonesi, auxiliary bishop of Rome. The parish itself had been erected on 13 November 1958 by decree of Cardinal Vicar Clemente Micara.

The parish was erected on 13 November 1958 by decree of Cardinal Vicar Clemente Micara, before the present church existed; the building was inaugurated in 1972. Pope John Paul II visited on 8 May 1983 and Pope Francis on 3 June 2018. The facade portico links the church to the other buildings of the parish complex.

The church stands in Lido di Ostia, the coastal frazione of Rome, at the coordinates 41.73661, 12.27223. A portico links the facade to the other buildings of the parish complex, so the entrance is reached from the adjoining courtyard. It is an active parish church, so visits fit around liturgical celebrations.

The church was visited by Pope John Paul II on 8 May 1983 and by Pope Francis on 3 June 2018. The parish itself was erected on 13 November 1958 by decree of Cardinal Vicar Clemente Micara, a decade before construction began.
