Gian Lorenzo Bernini, Sant'Andrea al Quirinale, 1658-70, Rome; commissioned by Cardinal Camillo Francesco Maria Pamphili for the nearby Jesuit seminary. Created by Beth Harris and Steven Zucker.
Brilliant! One footnote (literally): there were only three or four steps to the entrance originally; the street level was later lowered and that required additional steps which today consequently have more emphasis than Bernini intended.
Wow. The first view of the interior knocked my socks off, lol. I'm in love with the colored pillars (of all things)... But this is yet another place I could get lost in.
