The soap workshop was originally built in Sidon by the Hammoud family in the 17th century. During the 19th century (around 1880), the Audi family became the owner of the soap workshop and turned it into a family residence. It was abandoned in the 1980s when the Lebanon War broke out and the ground floor was occupied by refugees. In 1996, the Audi Foundation started to restore the edifice. The Soap Museum opened in November 2000.
