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 - in his distinctive style.

Borromini later became occupied by the construction of many components of the building such as the façade, two courtyards, the refectory, recreational rooms, the Biblioteca Vallicelliana, and the clock tower.

This panel-clad façade of the Oratorio dei Filippini was designed to mimic the human body with open arms for those wanting to worship there.

Today, a room in the Oratorio dei Filippini, known as the Sala Borromini, functions similarly to a town hall as meetings and debates are held there.

[3] In the staircase leading up to the library one can admire the full scale plaster models of Alessandro Algardi's reliefs of The Encounter of Attila and Pope Leo (the finished marble is in St. Peter's Basilica) and The Miracle of Saint Agnes (executed by Algardi's assistants Ercole Ferrata and Domenico Guidi; the marble version, destined to become the main altarpiece in Sant'Agnese in Agone was never made).
