The National Museum of the Middle Ages is currently undergoing renovations. These are expected to continue through mid-2021. The museum will be closed for a period of at least six months starting in June 2020; at other times, it will be partially open. Be sure to check the website for updates. The museum is home to a magnificent array of artifacts, including medieval sculptures, stained glass, and objets d'art. The museum is most famously known for its celebrated series of tapestries, The Lady with the Unicorn (1500). Other highlights include the ornate 15th-century mansion Hôtel de Cluny, and the frigidarium (cold room) of a Roman-era bathhouse.
