Al-Ahsa Oasis

Al-Ahsa is an oasis of around two and a half million date palms fed by artesian springs in the Eastern Province, generally described as the largest oasis in the world by that measure, cultivated continuously for several thousand years and supporting the towns of Hofuf and Mubarraz. It was inscribed as World Heritage in 2018 as an evolving cultural landscape, the property comprising gardens, canals, springs, wells, a drainage lake, historic buildings and archaeological sites. Qasr Ibrahim, an Ottoman-period fort with a domed mosque, stands in Hofuf, along with Qasr Sahood, the Jawatha mosque site, one of the earliest in the peninsula, and the Qaisariya souq.

History

Springs have drawn people and date-palm farming to this oasis since prehistoric times, and its old name Hajar may be the Agarum of Dilmun inscriptions, the home of the god Inzak, though other scholars place Agarum on Failaka island. The Rashidun Caliphate took Eastern Arabia in the 7th century, and in 899 the Qarmatian leader Abu Tahir al-Jannabi broke the region away from the Abbasids, with its capital at al-Mu'miniya near modern Hofuf; around 1000 Al-Ahsa is said to have been the ninth-largest city in the world, with 100,000 people. The Uyunids overthrew the Qarmatians in 1077 and were followed by the Usfurids and Jabrids, the Ottomans took the oasis in 1550 and were expelled in 1670 by the Banu Khalid, it passed to the Emirate of Diriyah in 1795, back to the Ottomans in 1818, to Nejd in 1830 and to direct Ottoman rule in 1871, and in 1913 ibn Saud annexed it to Najd (Wikipedia, Al-Ahsa Oasis).

What's there

• The palm gardens - the millions of date palms and their irrigation.
• Qasr Ibrahim - the Ottoman fort and mosque in Hofuf.
• Jawatha mosque - the early mosque site outside the town.
• Qaisariya souq - the covered market in Hofuf.

When to go

November to March; Eastern Province summers combine extreme heat with humidity. The date harvest in late summer is when the gardens are busiest. Mornings are best for the gardens.

Good to know

The property is a landscape spread over a large area, not a single site, and a car is needed to see it. Spring flow has declined and many traditional channels are dry. Qaisariya souq was rebuilt after a fire. Interpretation is limited in places.

Nearby

Jabal Al-Qarah lies within the oasis; Dammam is northeast.
