San Paolo Maggiore, Naples

I stumbled upon the old Greek agora/Roman forum of Naples, and much to my surprise and delight, I realized the church in front of me had built around the ruins of an ancient Roman temple dedicated to Castor and Pollux.It turns out that the front of the old Roman temple was in better shape until the 1688 earthquake. All that remains are two Corinthian columns, a couple of bases, and the knowledge that there are probably more entombed in the walls of the newer church.Talk about adaptive reuse.
