The Musée d'Art et d'Histoire du Judaïsme (mahJ) is the largest French museum dedicated to Jewish art and history. Located in the Hôtel de Saint-Aignan in Paris's Marais district, the museum showcases the rich history and culture of Jews in Europe and North Africa from the Middle Ages to the 20th century. Its collection includes religious objects, manuscripts, and works of art from artists like Marc Chagall and Amedeo Modigliani, highlighting the contributions of Jews to France and the world. The museum was conceived in 1985 and opened in 1998, with the aim of providing Paris with an ambitious museum dedicated to Judaism. The Hôtel de Saint-Aignan was chosen as the site due to its historical significance; during WWII, several Jewish inhabitants of the building were arrested and deported by the French Vichy government. The museum also features a bookshop, a media library, and an auditorium offering various cultural events. Guided visits in English are available during the tourist season. The museum's collection was assembled from three main sources: the Musée d’art juif de Paris, the Musée national du Moyen-Age, and long-term loans from other museums. The mahJ explores fundamental questions about Judaism and Jewish identity, and its collection is organized chronologically, situating the works of art in their historical context. It is a must-visit for anyone interested in Jewish history, culture, and art.
