Najran is the far south-west, on the Yemeni border - mud-brick architecture, and a pre-Islamic city still readable on the ground.
Al-Okhdood was a walled city on the frankincense caravan route north, and what survives is its outline: stone walls, foundations, and blocks carved with inscriptions and animals. North of the city, the wells at Himā were added to the World Heritage List in 2021 - roughly 7,000 years of travellers left inscriptions on the rocks around them, running through Musnad, Aramaic-Nabataean, South Arabian, Greek and Arabic. The wells still hold water.
Najran's own architecture is distinct: tall mud-brick houses with white-painted crenellations, closer to Yemeni building than to Najdi.
Getting there and when to go
Najran has an airport. It is remote, and very few visitors reach it.
