(CNN) — Incredible natural beauty, amazing archaeological treasures, historic cityscape -- what makes a destination worthy of UNESCO World Heritage status?
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.
Movers and shakers
The Prosecco Hills of Conegliano and Valdobbiadene in Italy are also being debated.
UNESCO concluded its deliberations by July 4.
The reef has been on the list for the past nine years, but after what UNESCO calls a "visionary" plan by the government of Belize, it's deemed no longer in extreme peril.
Fanjingshan mountain in China is also a nominee.
"Today's removal of the Belize Barrier Reef Reserve System from the List of World Heritage in Danger is a pivotal moment for the World Heritage Convention and the oceans," said Mechtild Rossler, director of the UNESCO World Heritage Centre, in a statement.
