, (watercolor by

rione was born after the
unification of Italy (such as
San Saba,
Testaccio and
Prati), from the convention, signed in 1886, between the
Boncompagni (heirs of the Ludovisi) and the Municipality of Rome. With this act, the
Lords of Piombino assigned to the housing development the area of Villa Ludovisi: about 25 hectares of park between the
walls and the historical
rioni of Trevi and Colonna, which between the 17th and 19th centuries had extended eastward up to
Porta Salaria (the present Piazza Fiume). This housing development, its events, its protagonists, can be considered an exemplary episode of the growth imparted by the
Savoys to the new capital; a growth based on speculative construction that attracted businessmen from around Europe and, in the space of not even twenty-five years, led the city from the
breach of Porta Pia to the economic crisis of the latter 1880s, to the
Banca Romana scandal. The technical and financial arm of the operation (uselessly deprecated by the European intellectuals of the time as an unforgivable ugliness) was the
Società Generale Immobiliare, established in
Turin in 1862, which followed the movements of the capitals of the Savoy kingdom moving its headquarters first in
Florence (in 1862) and then finally in Rome in 1880; here it became, for a century, the great protagonist of the Roman building speculation. The project for the development of the
rione can be dated back to 1870, when Rome became the new Italian capital: it is no coincidence that Prince Ignazio Boncompagni of Piombino had been one of the 18 members of the temporary city council (6 nobles, 4 bourgeois and 8 landowners and merchants of the countryside ) that, among its first acts, had established a Commission of architects and engineers to select the projects «
for the construction of new neighbourhoods in that part [of the city]
that is best suited to the new building». The concerned part was the high one, between the
Esquiline and the
Pincian Hill, already identified for its proximity to
Termini, where several entrepreneurs from Northern Italy and abroad had already started to build. Between projects, opinions and debates, the first master plan of the urban development of the "third Rome", signed by Alessandro Viviani, was launched in 1873, thus legitimising the 7 agreements with the Municipality of Rome for the construction of new neighbourhoods that had already been ratified "regardless". More than 10 years passed, during which both the new properties and the prices of the building areas went on growing, before an official and binding master plan was launched in 1883, based on a law of 1881. Although the latter Viviani master plan provided for the intangibility of Villa Ludovisi, the aristocracy of the town also wished to participate in the game; so it was that the prince in title at the time, Rodolfo Boncompagni Ludovisi, in 1886 signed an agreement with the Municipality and with the Società Generale Immobiliare for the urbanisation, the allotment and the «
building of a neighbourhood of private dwellings in the Villa formerly Ludovisi». The deal was however concluded on the eve of the crisis, which involved the Prince of Piombino and brought the Immobiliare on the verge of bankruptcy which was avoided in 1898 thanks to an arrangement with the creditors. After the acute phase of the crisis was over, the housing development found new vitality: elegant buildings had already been built on Via di Porta Pinciana, in 1890 the
Palazzo Margherita had been completed, in 1905 Villa Maraini, the Hotel Flora and the Hotel Excelsior arose and in 1906
Via Vittorio Veneto, the thoroughfare of the
rione, was completed. Another season of intense construction took place between 1925 and 1935, with the Hotel Ambasciatori, the
INA building and the headquarters of the
Ministry of Economic Development (born as
Chamber of Fasces and Corporations). ==Geography==
