Chiesa di Sant'Agnese in Agone

The church of Santa Maria dell'Anima, founded in the 14th century, was the church of the Holy Roman Empire in Rome and is today the national church of the German-speaking world. The oldest mention of the church dates back to 1389. In the 15th century, Santa Maria dell'Anima became a hospital for all inhabitants of the Holy Roman Empire who visited Rome. A lay brotherhood was also active, of which prominent citizens of the Holy Roman Empire residing in Rome became members, including William of Orange's eldest son, Philip William. Today, after bitter disputes, both the Belgians and the Dutch have a representative on the board. The church itself is now used exclusively as a parish for the German-speaking people of Rome. Since 1992, the Dutch have had the so-called Frisian Church (San Michaele dei Frisoni) at their disposal, in the immediate vicinity of St. Peter's Basilica.

The church of Santa Maria della Pace was consecrated in 1482 by Pope Sixtus IV on the site of an earlier chapel. In 1656-1667, Pope Alexander VII had the building restored by Pietro da Cortona, who added the famous baroque façade that juts out between the concave wings: this façade, which was intended to simulate a theatre stage, has two orders and is preceded by a semicircular pronaos supported by twin Tuscan columns.

Sant'Ivo alla Sapienza is a church built between 1642 and 1660 by Francesco Borromini, the architect of La Sapienza University. For its artistic, technical and symbolic values, the building is considered one of the masterpieces of the architect, of the Baroque and of the history of architecture in general. The works were conditioned by the pre-existence of the already built palace and courtyard, which left a very limited quadrangular space for the construction of the church. But the result is of extreme purity and apparent simplicity.
