Al Ahsa Oasis, situated in the Al Ahsa region of eastern Saudi Arabia, is the largest self-contained oasis in the world. Recognized as a UNESCO World Heritage site, the oasis encompasses a rich agricultural area with an impressive number of natural springs and palm trees. Al Ahsa is named after the Arabic word for the sound of water underground and has a history dating back to Neolithic times. It is a prime example of human settlement and agricultural development in a desert environment, with intricate qanat systems that irrigate the land. The oasis supports a variety of crops, including dates, which are a significant product from this lush area. With over 2.5 million date palms, it stands as a testament to traditional farming practices that have been preserved over centuries. Al Ahsa also houses historical sites such as the Ibrahim Palace, and the area has maintained a rich cultural heritage associated with its long history of human habitation.
