St. Charles Church (just a few hundred meters located from the place Mozart died) is one of Vienna's most impressing and significant buildings. Between April and October it is the ideal location to perform Mozart´s last work the REQUIEM. The concerts are performed by Choir and Soloists of the Salzburg Concert Society as well as by the Orchestra 1756. All together there are more than 40 musicians on stage. The Orchestra 1756 plays on so called historical instruments.
Mozart’s 250th birthday was used as an opportunity to found the Orchestra 1756 in 2006. The ensemble devotes to the interpretation of music between 1750 and 1800. The unique Mozart sound originates from intensive occupation with the stylistics of the 18th century, historic instruments and balanced formations of musicians. The Choir of Salzburger Konzertgesellschaft depending on the repertoire consists of 16 to 24 singers.
In 1713, one year after the last great plague epidemic, Charles VI, Holy Roman
Emperor, pledged to build a church for his namesake patron saint, Charles
Borromeo, who was revered as a healer for plague sufferers. An architectural
competition was announced, in which Johann Bernhard Fischer von Erlach prevailed
over, among others, Ferdinando Galli-Bibiena and Johann Lukas von Hildebrandt.
Construction began in 1716. After J.B. Fischer‘s death in 1723, his son, Joseph
Emanuel Fischer von Erlach, completed the construction in 1737 using partially
altered plans. The church originally possessed a direct line of sight to the
Hofburg and was also, until 1918, the imperial patron parish church.
As a creator of historic architecture, J.B. Fischer united the most diverse of
elements. The façade in the center, which leads to the porch, corresponds to a
Greek temple portico. The neighboring two columns, crafted by Lorenzo Mattielli,
found a model in Trajan‘s Column in Rome. Next to those, two tower pavilions
extend out and show the influence of the Roman baroque (Bernini and Borromini).
Above the entrance, a dome rises up above a high drum, which the younger J.E.
Fischer shortened and partly altered.
The Karlskirche overlooks Karlsplatz Stadtbahn station.The iconographical
program of the church originated from the imperial official Carl Gustav Heraeus
and connects St. Charles Borromeo with his imperial benefactor. The relief on
the pediment above the entrance with the cardinal virtues and the figure of the
patron on its apex point to the motivation of the donation. This sculpture group
continues onto the attic story as well. The attic is also one of the elements
which the younger Fischer introduced. The columns display scenes from the life
of Charles Borromeo in a spiral relief, however they also recall the Pillars of
Hercules and act as symbols of imperial power. The entrance is flanked by angles
from the Old and New Testaments.
This continues in the interior as well, above all, the dome fresco by
Johann Michael Rottmayr of Salzburg and Gaetano Fanti which
displays an intercession of Charles Borromeo, supported by the Virgin Mary.
The cardinal virtues surround the scene. The frescos in a number of side
chapels are attributed to Daniel Gran.
The high altar painting portraying the ascension of the saint was conceptualized
by the elder Fischer and executed by Ferdinand Maximilian Brokoff. The altar
paintings in the side chapels are by various artists, including Daniel Gran,
Sebastiano Ricci, Martino Altomonte, and Jakob van Schuppen.
As strong effect emanates from the directing of light and architectural
grouping, in particular the arch openings of the main axis. The color scheme is
characterized by marble with sparring and conscious use of gold leaf.
Next to the structures at Schönbrunn Palace, which maintain this form but are
more fragmented, the Karlskirche is Fischer‘s greatest work. It is also an
expression of the Austrian joie de vivre stemming from the victorious end of the
Turkish Wars.
The Requiem has a mysterious history, riddled with deception and manipulation. The work was commissioned by Count Walsegg in July 1791, who wanted to pass off the work as his own, so the circumstances of the commission were kept secret. Upon Mozart's death, Constanze (his wife) had the work completed by other composers, but in order to receive the final payment, their assistance had to be kept secret.
At the same time, Constanze wanted to present the Requiem as being entirely written by Mozart, in order for her to make the most of it. When it became known that others except Mozart assisted with the Requiem, Constanze insisted that Mozart left explicit instructions for the work's completion. Many claimed that Antonio Salieri played a role in the completion and commision of the Requiem as well as involving him in Mozart's death.
The Requiem played, is the one completed by Franz Xaver Süßmayr. The performance lasts approximately one hour.
