Congrégation de l'Oratoire
The Oratorio dei Filippini (Oratory of Saint Philip Neri) is a building located in Rome and erected between 1637 and 1650 under the supervision of architect Francesco Borromini. The oratory is adjacent to the Chiesa Nuova Santa Maria in Vallicella, the mother church of the congregation. In front of the two sides was a small closed square, now integrated in the Corso Vittorio Emanuele II.
