The Arch of Hadrian (also called the "Arches of Capua" or the "Lucky Arch") is an ancient Roman triumphal arch located in Santa Maria Capua Vetere (ancient Capua, now in the Province of Caserta, southern Italy). It was originally a triple arch, but today only three pylons and one of the lateral arches survive. It spanned the Appian Way and constituted an ideal entrance to the city, perhaps corresponding to the line of the pomerium.
