Located in an old soap factory dating from the 17th century, this is Lebanon’s only museum of that most humble yet indispensable of products. Well laid-out, with trilingual explanations (Arabic, English, French) on the art of ‘saponification’ (which we nonsaponifiers might simply call ‘soapmaking’), the museum also has a stylish cafe and a boutique with some lovely illustrated history and cookery books. Both entry and guides are free.
