Among the few surviving medieval structures in Paris, the Tour Jean-sans-Peur stands out for its remarkable history. Located outside the city’s 4th arrondissement, this ancient tower is a rare vestige from the Middle Ages, offering a glimpse into the city’s distant past.
The tower was originally a section of l'hôtel de Bourgogne, a grand castle that once belonged to the powerful Dukes of Burgundy. While the castle itself no longer exists, the tower serves as a testament to the wealth and influence of its former residents. Its walls have witnessed centuries of Parisian history, from noble feuds to dramatic political changes.
Tour Jean-sans-Peur now sits amid modern buildings, creating a striking contrast between old and new. Visitors can still admire its fortified stone construction, which has endured through wars and revolutions. The tower’s intricate stone staircase and defensive architectural features offer insight into medieval life and design in the heart of the city.
