Well, it's the Aqueduct of Segovia in Spain, but not she's not Sophia Loren. It's Debbie Reynolds who was filming "It Started with a Kiss" with Glenn Ford at the same time "Spartacus" with Kirk Douglas was filming. They all stayed at the Madrid Hotel together during filming. The aqueduct was in Spartacus, of course, and maybe in "It Started..." (?), but either way, it's gotta be the Lincoln Futura.
