Even though the Torlonia Palace has lost its original characteristics, it still remains an interesting example of 16th -17th century living and it contains several rooms frescoed with thematic paintings. On the inside there is a wonderful white garden which contains only plants bearing white flowers in keeping with an ancient tradition. The present appearance of the Church of the Conception is the result of numerous transformations it has undergone over the years including the foundations. The only original part still preserved today is the apse while the façade dates back to the 18th century. From the 14th century it was dedicated to St. Felice Papa, who remained entitled until 1851 when the title passed on to The Immaculate.
