The owners of Palazzo Montani-Leoni, in corso Tacito, today location of the Cassa di Risparmio di Terni e Narni Foundation, were furious, when around the year 1870 the Municipal decided to demolish part of the open gallery and the colonnade in order to build the "new road" in other words, Corso Tacito.
Corso Tacito was built, in fact, by demolishing small houses and cutting the "superfluous" parts of the larger ones. Palazzo Montani-Leoni was to survive but would be distorted by the demolition of the inside courtyard and garden and- precisely- the open gallery and most of the colonnade. The owners put their foot down. They demanded that the Municipal should not limit itself to just expropriating what they needed but that they should purchase the entire building. And so they did, and some years later, the Municipal sold it all to the Cassa di Risparmio. The 16th century building was, however, by now irredeemably damaged in its appearance and now only a few elements remain of the original facade, first of all the portal, while the rest has all but disappeared due to various revamps. A few testimonies can be found on the inside, but, what is valuable today is the art collection belonging to the bank Foundation.
Joined into one building with the Foundation location, next to Palazzo Leoni-Montani, stands the new construction which hosts the bank, the old Cassa di Risparmio, which moved into it when it was established in 1846, when on the same site there was noble tenement which became anonymous due to the amputation undergone for the construction of the new high street and in which the Charity Congregation had its offices
This building was demolished and substituted with a more modern and functional one which was inaugurated in 1966 and built according to a project by the architect/engineer Cesare Pascoletti, an expert in the building of banks, having already designed, among others, the Banca Nazionale del Lavoro building in Bari and several other Cassa di Risparmio banks as well as the Terni one. It is a building which stands out from all those around it, in a combination of modernism and ancient buildings which had further, and mostly more fulgent, examples. It is a large cube, in Pascoletti's typical style, with abundant use of coloured glass windows and markers. The only typical reminder of Terni is the use of sponge stone for the outside coatings.
