Santa Rosa da Viterbo is a modern parish church at Via Santa Giovanna Elisabetta 53 in the district of Tor di Quinto, in the south-east of the suburban area of Tombe di Nero. Picture of the church at Wikimedia Commons. 
The dedication is to St Rose of Viterbo.
It was completed in 1995 with a nave and aisles and a large enclosed narthex, and is sited longitudinally to the street. The external walls are polychrome, with the lower courses in yellow brick, followed by a wide stripe in bluish-grey concrete and then the rest up to the pitched and tiled roofs in dull pink render. The street side has a large arched window in the narthex, and two in the main body of the church with recessed surrounds in creamy white continuing up to the roofline. These windows have stained glass to an abstract design, and the two nave windows have small rectangular windows above them with little balconies formed of quarter-sections of spheres.
The monumental entrance is reminiscent of corporate headquarters buildings of the period, and is topped by a semi-cylindrical glass canopy inserted into the pitched roof of the narthex to form a skylight. This frames a large window in the actual entrance façade, and either side of this are two protruding concrete panels which continue up above the narthex roofline and which have a large rectangular aperture each at their tops. The bottoms of these panels form the sides of the porch canopy, which has a flat roof. Very unusually, large pot plants are cultivated on the roofs of porch, narthex and the church aisles. This is a singular and enjoyable church building, well worth a visit.
