Piazza Carlo Felice

In 1850 the enlargement plan of the capital was launched; it was structured in three partila levels for the areas outside Porta Nuova, Valdocco and Vanchiglia.

In the first of these levels, approved in 1851, the Municipality, owner of the great part of the lands, ran the operation, from the selling of the lands to the realization of the development buildings, on the indications by the architect Carlo Promis, who developed everything, from the drawing of the route of a road to the architectonic decoration.

Piazza Carlo Felice

The core of the intervention is piazza Carlo Felice. Its characteristic is due to the homogeneous treatment of the façade of the porticoed buildings, covered for three floors by a slightly relieved ashlar-work, finished with an attic of semi-pillars.
Those façades melt themselves towards north to the head of the Contrada of Porta Nuova (later become via Roma), designed in a semi-octagonal shape by Gaetano Lombardi in 1822, while towards south they turn along the Strada del Re (later Corso Vittorio Emanuele II).

In 1859 the fountain of the Società per la Condotta dell'Acqua Potabile was inaugurared; the following year Jan Pierre Barillet Deschamps drew the central garden realized by Marc Louis Quignon.

Piazza Carlo Felice and the two minor piazza Paleocapa and Lagrange constitute at the same time the new entrance to Turin from south, the confirmation to the morphology inherited by the modern city and a morphological model for the development of the 19th century city.
