Unsurprisingly, Oman is home to four UNESCO World Heritage Sites. The Bahla Fort is one of the most well-known forts in the country with its original stone foundation still in good condition today. The irrigation systems of Al Aflaj are of utmost cultural importance as a testament to ancient irrigation methods from 500 AD that are still in use today. The archaeological sites of Al Khutm, Bat and Al Ayn are also heritage sites as they contain vital remains of settlements and buildings from the Bronze Age. Lastly, the land of Frankincense, near the Al Falaj Hotel, is also a heritage site as it showcases important trade routes which were instrumental in the success of the Frankincense industry.
