By the 11th century gold, slaves and ivory were the hot commodities being traded between Marrakesh and Guinea. Evolving through the ages to cater to the popular trade of the day, the major industry here today is fishing connected to the country's sardine industry, but there is also an economy based on exported phosphates, textiles and ceramics. The city was overseen by the Portuguese Empire in the 1500s, and a fortress built to safeguard the city by these Portuguese influences still stands today. Safi sits near the foothills of the snow-capped Atlas Mountains where Bedouins once camped.
