Porte Saint-Denis is a historic and significant landmark in Paris, located in the 10th arrondissement. This monumental triumphal arch was built in 1672 by architect François Blondel and sculptor Michel Anguier at the request of King Louis XIV. The Porte Saint-Denis once served as a gateway through the Wall of Charles V, a medieval fortification constructed between 1356 and 1383 to protect the Right Bank of Paris.
