The palace church, which now serves as the parish church of Augustenborg, is open to the public in the summer months.

The northern wing includes the impressive Schlosskirche (palace church) and the law section, as well as Mannheim's lower district court.

The palace church was consecrated in 1745.

It featured a throne room, a palace church and a royal residential part and encompassed 4872 m2.

After the religious service in the Romanian Orthodox rite, the cortege walked through the palace gardens to the burial place next to the palace church.

As concertmaster, he assumed the principal responsibility for composing new works, specifically cantatas for the Schloßkirche (palace church), on a monthly schedule.

The dome of the palace church rises 92 meters (302 feet).

The most extensive change was probably the demolition of the Eggenberger palace theater, in the place of which a baroque palace church was established.

It was during this phase that the Eggenberg palace theater was converted into a palace church in the Baroque style.

Westerly located additional structures and a palace church are of a later period, dating to the 13th/14th century.
