The Tour Jean-sans-Peur or Tour de Jean sans Peur (English: Tower of John the Fearless), located in the 2nd arrondissement of Paris, is the last vestige of the Hôtel de Bourgogne, the residence first of the Counts of Artois and then the Dukes of Burgundy. The tower contained bed chambers and the grand stairway of the original residence, which stood next to it. It was completed between 1409–1411 by Jean sans Peur. The original hôtel occupied about a hectare of land, the boundaries of which are now marked by the rues Étienne Marcel, Montorgueil, Saint-Sauveur, and Saint-Denis. The tower itself is located at 20 rue Étienne Marcel, in the courtyard of an elementary school. It is one of the best surviving examples of medieval residential architecture in Paris. The tower is open to the public and presents changing expositions on life in the Middle Ages.
The first hôtel particulier or manor, on the site was built by the Counts of Artois, whose domains included most of northern France and Flanders. In 1270, Robert II, Count of Artois, the nephew of king Louis IX, known as "Saint Louis", bought several houses and about a hectare of land in the northern part of the city, adjacent to the wall of Philippe Auguste, the first city wall of Paris, which had been built between 1190 and 1290. Part of the land was outside the wall, the other part within Paris. As the city grew, a new wall built by Charles V, completed in 1383 brought the entire property within the city limits. Little is known about this first hôtel, which was largely rebuilt by its later owners.
In 1369 the hôtel passed to Philip the Bold, the Duke of Burgundy, by his marriage to Marguerite, the Countess of Flanders and of Artois. The records of the concierge of the house show that between July 1371 and Easter 1375, he carried out important construction works, including the building of a tower. After Philip's death in 1404, it became the property of Jean de Bourgogne, better known as Jean sans Peur, or John the Fearless.
