Santi Fabiano e Venanzio a Villa Fiorelli is a modern parish and titular church on the Piazza di Villa Fiorelli in the Tuscolano district. The postal address is Via Terni 92. Pictures of the church on Wikimedia Commons. 
The parish of SS Fabian and Venantius was erected by Pope Pius XI in 1933, and dedicated to Pope St Fabian and St Venantius of Camerino (both martyred in the persecution of the emperor Decius, c. 250). The church was opened for worship in 1936, but not formally consecrated until 1959 by Msgr. Luigi Traglia. It was designed by Clemente Busciri Vici.
It is the regional church of Camerino since Santi Venanzio e Ansovino was demolished in 1928, and contains some rescued artworks from that church. St Venantius is the patron of this region. The parish is served by diocesan clergy.
The plan is rectangular, with a shorty presbyterium at a lower elevation leading into a three-sided apse.
The nave has aisles, and all the roofs are pitched and covered with brown tiles. Unusually, the aisle roofs are hipped from each end of the aisles. All the walls of the church are rendered in a light purplish pink.
The entrance façade looks very odd, because the gable is actually false and is raised above the roofline with the help of diagonal buttresses which rise above the lateral eaves of the nave. This allows for three large arched apertures to be inserted below the gable, the central one higher and containing a cross of thin metal rods. The section of the nave frontage containing the entrance is recessed under a string course bearing a dedicatory inscription, this also forming the lintel of the doorway. The bronze door is decorated with symbols of air warfare, and the doorcase has wide stone uprights which step inwards. To the left of the door is a stone plaque commemorating the visit of Pope Pius XII on 13 August 1943, the date of the second air bombardment of Rome. To the right is another one recording the names of victims of the bombs that dropped in the parish. The rest of the nave frontage, above the string course, is blank wall bearing the coat-of-arms of Pope Pius XII. The aisle entrances, smaller than the main one but of the same style (except that they have their own lintels) are inserted into projecting three-sided enclosed porches with narrow arched windows on the other two sides. These contain geometric tracery. Above these porches, the aisle frontages bear a large round window each with stained glass in a Greek cross.
The aisle walls have large arched windows, and there is a campanile attached to the right hand side of the church just before the presbyterium. It is a blank-walled tower with a large arched soundhole on each side and a flat cap.
The interior is rendered in beige, with a white ceiling which is slightly coved. The narrow but tall aisles do not have arcades, but columns in green marble with imposts (but no capitals) support the low windowless upper wall of the nave. The apsed presbyterium has a flat ceiling with a recessed motif of a cross within an arch. There is an arched window either side of the apse, and the three sides of the apse itself are entirely covered by a spectacular mosaic of Christ blessing SS Fabian and Venantius. The altars at the ends of the aisles come from the demolished predecessor church.
The feast of St Fabian is celebrated on 20 January, and that of St Venantius on 18 May.
