The Porte Saint-Martin (, St. Martin Gate) is a Parisian monument located at the site of one of the gates of the now-destroyed fortifications of Paris. It is located at the intersection of the Rue Saint-Martin from the south, the Rue du Faubourg Saint-Martin from the north and the grands boulevards Boulevard Saint-Martin from the east and Boulevard Saint-Denis from the west.
The Porte Saint-Martin was designed by architect Pierre Bullet (a student of François Blondel, architect of the nearby Porte Saint-Denis) at the order of Louis XIV in honor of his victories on the Rhine and in Franche-Comté. Built in 1674, it replaced a medieval gate in the city walls built by Charles V. It was restored in 1988.
The Porte Saint-Martin is a heavily rusticated triumphal arch, 18 meters high, built in limestone and marble. Recesses are occupied by bas-reliefs:
