In the period in which industrialisation was almost completed- at least one part- the city found itself spontaneously expanding towards the east. The houses of the working class sprung up there, a few new factories had been built there, such as Bosco and la Carburo di Calcio, the latter had to then build a plant far from the city centre (it moved to Papigno) due to its emissions which provoked a number of complaints from those living in the neighbourhood. As well as a wide, new road that led to the train station, via Curio Dentato, a new, large church dedicated to Sant'Antonio was requested.
In Sant'Antonio church, the designer Cesare Bazzani, one of the architectural names that " marked" Terni, gives vent to his classical setting, to the point of filling the facade of a modern church like Sant'Antonio with references to mannerisms. Sant'Antonio, the most classical of Tern's churches, was built between 1923 and 1935, exactly opposite the villa of the industrialist Bosco, another of Bazzani's projects. who, in the same neighbourhood, also "signed" the Regio istituto tecnico industriale (Technical high school for Industry).
It was the new part of the town which was emerging just after the war. The church was built close to the medieval city wall which underwent further chagrin, and just a few steps away from Porta Spoletina, which was one of the most important in Terni.
The use of "gigantism" is not lacking in the church of Sant'Antonio either, of its shapes and arches, with the vast outside stairway, and the large central portal included inside an archway, which virtually marks the entire facade.
