Explore the architectural gems of Le Marais—one of Paris’s most charming and culturally rich districts. The 17th century saw a boom in the construction of private mansions (known as hôtels particuliers) in this area. While many were lost to the French Revolution or the passage of time, several remarkable ones remain. Here are five must-see Marais mansions that showcase the district’s historical and architectural heritage.

5. Hôtel d’Angoulême Lamoignon
Starting off our curated list is the Hôtel d’Angoulême Lamoignon, situated at the intersection of Rue Pavée and Rue des Francs-Bourgeois. This historic mansion now houses the Bibliothèque Historique de la Ville de Paris (Paris Historical Library). Be sure to wander into the serene garden located at the rear entrance on Rue des Francs-Bourgeois—it’s especially enchanting when softly illuminated in the evening.
4. Hôtel Carnavalet
Just a short stroll from Hôtel Lamoignon lies the Hôtel Carnavalet, one of Paris’s oldest surviving townhouses and a rare example of Renaissance architecture in the city. Built between 1548 and 1560, it now serves as the Museum of the History of Paris. While it holds deep cultural value, time-conscious travelers might consider prioritizing the Louvre Museum for more iconic artworks if their stay is brief.

3. Hôtel de Sens
A medieval marvel in the heart of Le Marais, the Hôtel de Sens stands alongside the Hôtel de Cluny as a rare surviving example of Gothic residential architecture in Paris. It once hosted Queen Margot, the estranged wife of King Henry IV, around 1605. Today, it operates as a fine arts library, and its original towers still rise proudly above the street—making it a must-visit for fans of medieval architecture and Parisian history.

2. Hôtel de Beauvais
Among the most fascinating stories in Le Marais is that of the Hôtel de Beauvais. Built for Catherine de Beauvais, a controversial figure known for her peculiar looks and stingy nature, this mansion became the temporary home of the Mozart family during their European tour. Catherine was also a tutor to young Louis XIV, with the idea that her lack of beauty would keep the king focused on learning. This mansion stands out for its compelling backstory and well-preserved design.

1. Hôtel de Sully
Topping our list is the Hôtel de Sully, one of the best-preserved aristocratic residences from the 17th century. This exquisite building exemplifies the architectural style of that era. Part of it was designed by Louis Le Vau, the famed architect behind parts of the Palace of Versailles. Located near Place des Vosges, visitors are encouraged to enter through the discreet side gate tucked into one corner of the square, offering a hidden passage into one of Le Marais’s most impressive architectural treasures.

Whether you’re a history enthusiast or an admirer of classic Parisian design, these Marais mansions offer a unique glimpse into the city’s aristocratic past.
