In the middle of the main rotunda above the place of visions the altar of grace of a singular beauty is to be seen showing the 14 holy helpers. The elegant style is in the taste of rococo. The idea of an altar standing in the centre of a church was an invention of Küchel. The plans are supposed to back to Johann Michael Feichtmayr in charge of the stucco. Since 1804 the tiny models of 30 cm hight are in the parish - church of Strullendorf near Nuernberg.
The altar is surrounded by a grating in the form of a heart where communicants receive Holy Communion. It is carved of wood skilfully. 4 holy helpers are standing on it. On the side of the high altar the visitor can catch a sight of the place of vision: It is a little chamber with four pictures showing the visions painted on canvas. The place of vision itself is empty. The part below consists of large curled volutes, rocailles and bows made of colourful stucco marble. It carries a canopy which sets free the sight to the high altar. From there you can see Banz Convent if the main door of the basilica is open. It reminds of a magnificent carriage carrying the 14 holy helpers. 12 - Four each are placed on three storeys; St. Catharine and St. Barbara are located on the lateral altars.
