Interior view
by JUVARRA, Filippo, Photo
In the Superga, Juvarra’s masterpiece, the architect combined in one building the two principal types of domical structure: the Pantheon type, where the dome rises from the cylindrical body, and the Greek-cross type, and these two different centralized systems remain clearly discernible. The body of the church is octagonal, as it should be in a Greek cross with beveled pillars; and the transition from the octagon to the circle is boldly conceived, for the circular entablature is set into the octagon touching it only in the centre of the four arches.
The photo shows the view into the dome.
