The site of Edge of the World on the north west of Riyadh has become a popular destination among Riyadh residents thanks to its green wadi and impressive cliffs located on the Tuwaiq escarpment which is one of the most prominent natural features of Saudi Arabia as it spreads over 1 000 kilometers from the province of Najran on the south up to Qassim in the north. But if you take a more southern access to the top of the cliff you will find a similar place that is less known although it is closer to the city and it hosts some unique features such as the natural spur called Khashm Zubaydah and the nearby natural pillar called Faisal's finger. Those places are in fact accessible directly from the Jeddah Highway, west of Riyadh, as just a couple of kilometers passed the checkpoint on the way to Makkah is an off-road access on the right side of the highway leading to a track that runs all along the Tuwaiq cliffs towards the north.
While driving on the track will appear a first type of feature that is not found in Edge of the World but in the surroundings of Khashm Zubaydah which is some stone structures that lay on the side of the track. Those manmade circular-shape structures are probably tombs that date from the Bronze Age (3rd millennium BCE) similar to the ones that are found in great numbers 100 kilometers on the southeast in Al-Kharj. But the ones that were built close to Khashm Zubaydah present a collection of very rare types of stone structures. Indeed if some of them have the common half a meter high circular shape with the burial chamber in the center, one structure only presents the circle but not the burial chamber, another one is tower-shaped (which is a feature more common to Oman), and a third one was inserted in a more complex a larger structure whose function is unclear.
