A visit to a historic district in Paris, Le Marais (The Marsh) through its rich history. From 1240 when the Order of the Temple built their fortified church outside the walls of the city; to the 17th century, as it became the favorite place of the aristocracy; to the 19th and 20th century when Le Marais turned into a commercial area; to the mid-1950s as a campaign of rehabilitation of the various Hôtels particuliers was launched. Now this is 1962 and the film ends with a description of the Place des Vosges.
