Marib Dam, Rock-fill gravity dam in Marib Governorate, Yemen
Marib Dam is a stone barrier in Marib Governorate that extends 763 meters across the Adhanah valley and reaches a height of 38 meters. The structure sits at an elevation of 1146 meters above sea level and creates a reservoir holding 398 million cubic meters of water.
A kingdom known as Saba built an early version of the barrier at this location during the 8th century BC to store water for farming. The current structure was completed in 1986 near the ancient remains and follows similar principles of water retention.
The dam holds deep significance in Yemen's heritage, with references in the Quran and connections to the ancient kingdom of Saba's agricultural practices.
The valley sits in a dry region where temperatures can climb sharply, so morning hours offer more comfortable conditions for a visit. Paths around the site are mostly unpaved and may become difficult to walk on during rain.
The barrier stands close to ruins that show how early engineers created complex sluices and channels to irrigate fields in the desert. In 2023, UNESCO recognized the site along with other Sabaean locations as part of the World Heritage List.
