The Jesuit church was built between 1733 in 1756 as the Court Church of the Mannheim electors Charles Philip III and Charles Theodore to a design of the Italian architect Alessandro Galli da Bibiena. It was completed in 1760 and consecrated to St. Ignatius of Loyola and St. Francis Xavier by the Prince Bishop of Augsburg, Joseph of Hesse-Darmstadt.
Features of the exterior are the twin towered facade of red sandstone, the statues of the four cardinal virtues, the Pheme, by Baroque sculptor Paul Egell, which adorns the 75 m-high dome.
The marble pilastered interior is in a late Baroque-early classical style. Egid Quirin Asam from Munich was instructed to decorate the church. He decorated the dome with scenes from the life of the order's founder, St. Ignatius of Loyola, while the nave had an over 400 square metre fresco whose content referred to the subject of the high altar, namely the Mission of St. Francis Xavier to India.
On the occasion of city's 300th anniversary in 1906 the church was extensively renovated. The two statues of the founders of the Jesuit order in the lobby are by the sculptor Thomas Buscher. During the Second World War, the church suffered severe damage from British and American air attacks, especially the choir and the dome. After the war it was decided to rebuild the church in its historical style with the use of original parts in the reconstruction of the approximately 20 metres high marble altar of Peter Anton von Verschaffelt, and the electoral pews.
Even today, this church is still very rich in Baroque art. It has, the six side altars and font by Verschaffelt. In the crossing beneath the dome there are four frescoes representing the continents by the Mannheim Baroque painter Philip Jerome Brinckmann. The confessionals were reconstructed like the electoral pews. The most important sculpture is the 1747 'Crowned Silver Madonna' of Augsburg silversmith, Joseph Ignaz Saler. The destroyed frescoes by Egid Quirin Asam were not restored. Today's pulpit was only placed here after the war. It was created in 1753 and originally came from the Carmelite convent in Heidelberg. In the lobby there are very richly ornamented wrought iron gates made by the Mannheim master locksmith Philip Reinhard Sieber in 1755 and two monuments of the church from 1906.
The main organ case in the west gallery is built according to a design of the elector’s court sculptor Paul Egell. It survived the bombing and the small damage it suffered was repaired in 1952. In 1965 an instrument from the workshop of Johannes Klais of Bonn was installed. In 2004 this was optimized acoustically. The four manual organ has 62 registers. In the left side gallery is the choir organ. The case is by an anonymous artist. It was constructed for the Catholic Church in Fuerth in Odenwald in 1751/52. In 1961 it was transferred to Mannheim and contains 16 registers from the case of the post-war Egell organ. The instrument is now technically unreliable and will be replaced by a new one.
To take into account the current requirements of the liturgy the high altar was reconstructed and the choir redesigned. Klaus Ringwald created an altar of silver and bronze, with a new design of the sanctuary and four very large candlesticks. In the new marble floor of the nave a memorial plate with the names of the Jesuits buried in the crypt together with the name of the longtime rector and the Mannheim honorary citizen Fr. Joseph Bauer.
References:Sigmaringen Castle was first mentioned in the year 1077 in the chronicles of Petershausen monastery. The oldest parts of the castle are concealed beneath the alterations made during the 17th and the 19th centuries. The secret of the earliest settlement built on this defendable rock will never be fully revealed: large-scale excavation work would be necessary, which the extensive land development renders impossible. Judging from the many Roman remains unearthed in the area around Sigmaringen, the 12th century keep known as the 'Roman Tower' could be traced back to a Roman predecessor.
The castle remains that have been preserved (gate, great hall and keep) date back to the Staufer period around 1200. The castle remains were integrated into subsequent buildings. The foundations of the castle buildings are to a large extent identical to the surrounding castle wall.
These remains give us a good idea of how the castle might have looked during the 12th century.
