Arch of Gallienus

The Arch of Gallienus is a triumphal arch in Rome constructed from travertine stone with Corinthian capitals decorating its pilasters. The structure stands as a single arched opening integrated into the urban landscape along Via San Vito.

The structure originally formed part of the Servian Wall and was rededicated in 262 CE to Emperor Gallienus and his wife Salonina. This repurposing occurred during a turbulent period when the empire faced severe political and military challenges.

The arch was named to honor Emperor Gallienus and carries an inscription praising him as a merciful leader. Visitors can read how Romans used such monuments to celebrate their rulers and communicate political messages to the public.

The arch is located along Via San Vito near Vittorio Emanuele subway station, making it easy to reach by public transport. The site sits at street level in an active urban area, so visitors can view it while walking through the neighborhood.

The arch originally had smaller side openings for pedestrians that were removed during 15th century renovations. Historical drawings from that era show these lost passages and reveal how the monument looked before these changes.
