Baelo Claudia is situated on the northern shore of the Strait of Gibraltar. The town was founded in the end of the 2nd century BC as a result of trade with North Africa (it was a major port for Tangier, in Mauretania Tingitana, for example). It is possible that Baelo Claudia had some functions of governmental administration, but tuna fishing, salting, and the production of "garum" were the primary sources of wealth. The city was eventually successful enough to be granted the title of "municipium" by Emperor Claudius.
