ARABIAN SEA

TRADE IN the resin of the Boswellia tree made great wealth for those who controlled it: the farmers, the traders, the shippers and cameleers. The most famous frankincense empire was the Nabateans, who built Petra, but Salalah (Oman) and Hadhramaut (Yemen) were also key players.
Remains of this historic business can be seen in the souqs as well as ancient ruins along the beautiful coast.
