The Jubilee Church designed by Richard Meier in Rome is one such example, although a modern day take on religious space it is without question magnificent.
Robert Angelis created a 3D model of the church as part of his degree thesis, taking 2 months to render the animation is one to sit back and watch, the quality speaks for itself:
The Jubilee Church, whose religious title "Dives in Misericordia" is derived from the Letter of St. Paul to the Ephesians chap. 2.4 (God, who is rich in mercy), is the jewel in the crown of the Vicariato di Roma (Arch Diocese of Rome) Millennium Project.
The project features concrete, stucco, travertine, soaring glass skylights and three dramatic shells or arcs evoking gliding white sails. Unprecedented in Richard Meier's work, the concrete arcs are graduated in height from 56 to 88 feet.
