Believed to date from the 14th century when it was used by Egyptian merchants, this dilapidated khan is home to one of the city's most famous businesses, Sharkass . Making olive-oil soap since 1803, this family-run company produces good-quality, authentic Tripoli soap; you’re welcome to buy a bar of natural or perfumed soap, or simply to look around. Note that the shop is on the 1st floor (not the one with the same name on the ground).
