Just visited an amazing place an ancient castle, fortress that sits on a water basin, it actually has underground water systems that supplied the whole cities water needs. Water still flowing but not fully operational.
Sitting on top of a mountain in the northwest corner of Saudi Arabia is a mud and stone structure known as Za’abal Castle (or Zaabal Fort, Zaabal Palace). But it’s more than just a fortress, it sit on top of a well system that has run throughout the city of Sakakah for centuries.
