UNESCO's World Heritage Committee met in Manama, Bahrain to debate which sites to add to its catalog.
Among those awarded World Heritage Status were the Ancient City of Qalhat in Oman, known for its incredible archaeological remains, Al-Ahsa Oasis, an evolving cultural landscape in Saudi Arabia, and Kenya's Thimlich Ohinga archaeological site.
In total, 19 sites were added -- and the extension of one site was also approved.
The UNESCO World Heritage Committee meets annually to review additions to the list, which must be deemed of "outstanding universal value" to warrant inclusion. Representatives from 21 countries assess the options.
The first list was published in 1978 and included Yellowstone National Park in the United States and the Galapagos Islands of Ecuador.
Four decades later, UNESCO World Heritage status is highly coveted among tourist destinations across the world, often credited with bringing in more visitors.
This year's additions fall into different categories. Some are cultural properties such as the Caliphate City of Medina Azahara, a palatial city built in the 10th century near Cordoba, Spain. This one-time Arab Muslim medieval town is now a collection of vast, beautiful ruins.
Natural sites have also made the cut. These include South Africa's Barberton Makhonjwa Mountains and the awe-inspiring Fanjingshan mountain in China.
