The large square is surrounded by a sober and elegant wrought iron gate, supported by a foundation and white marble columns.
The building was left incomplete (with only perimeter walls, no plaster, a rough ceiling and a concrete floor) until 1922 to 1923, when devotion to St Therese of the Child Jesus began to spread.
The Gothic style church is presented in rare splendour with polychrome marbles, sculptures, mosaics, windows, paintings and decorations.
On the large wall behind the façade is a fresco by Ugo Bargellini of Florence, which depicts the apotheosis of the Carmelite, with details of Saint Therese of the Child Jesus.
The statue is dressed in a Carmelite habit, wearing the veil that Teresa had worn for several years in the monastery of Lisieux, and bears a reliquary chest in silver filigree containing a vertebra of the saint.
