This project started as a half-cube, which then got its corners chamfered off to become an octagon. It then had a large spherical central space carved out of its inside, in grand imitation of the archetypal Pantheon in Rome, but here rendered in simple brick, without the fuss of the Orders or coffers. Typically, the entrance to a central sancto sanctorum like this is given directly from the outside, but this project forces one to ambulate first through smaller domes at the corners before entering the central space, which is shown in the diagonal section below.
