The Pasteur Museum is housed in the apartment where the great scientist spent the last 7 years of his life. Hardly touched since that time, the museum is full of personal memorabilia and scientific instruments. Pasteur is buried on the grounds in a flamboyant mosaic-decorated mausoleum. The museum was closed to individual visitors for security reasons after the 13th November 2015 Paris terrorist attacks.
