The Pantheon of Rome was originally built in the first century BC and then rebuilt in 126 AD. Sitting at the heart of the Roman empire, it was a temple to all the gods. As Christianity came to dominate Italy, this pagan temple was rechristened as a Catholic church, the Santa Maria della Rotonda. Standing in front of the real thing is a breathtaking experience. It's huge and completely dominates the surroundings. Luap31's LEGO version, shown here, doesn't come in at quite the same scale, but is a really nice build.
