Another testimony to the importance of pearls and pearling to Bahrain was the creation of the ‘Pearling Trail’ on the Bahraini island of Muharraq. The Trail, recognized as a UNESCO World Heritage Site on June 30, 2012, is 3.5 km long and was used by pearl divers during much of Bahrain’s history. The site is the last remaining example of the cultural tradition of pearling and the wealth it generated at a time when the trade dominated the Gulf economy.
