At-Turaif is a mud-brick citadel on a limestone promontory above the Wadi Hanifah, built in 1766, where the first Saudi state had been founded in 1727. It was inscribed by UNESCO in 2010 for its Najdi architecture — thick sun-dried walls, narrow lanes, triangular decorative windows, flat roofs on palm trunks and tamarisk beams. A company owned by the Public Investment Fund is master-developing fourteen square kilometres around it.
2 · ⚑ The design code is the entry
Everything low-rise. Everything in the Najdi vernacular of the old town. The commercial heart laid out to be walked rather than driven. That is unusual anywhere and close to unique in the Gulf, where the neighbouring entries in this group — Downtown Dubai at LHL-S-245 Downtown Dubai, Lusail at LHL-S-255 Lusail, Doha — are defined by towers. Diriyah is the same region and the same decade making the opposite decision, and the Library holds the three adjacent so that is visible.
3 · What is actually open
At-Turaif and Bujairi Terrace since December 2022: fifteen thousand square metres of pedestrianised alleys holding more than twenty restaurants facing the World Heritage site across the wadi, which took more than a million visitors in its first six months. Diriyah Art Futures, the Zallal scheme and the 134-room Bab Samhan have followed. Thirty-eight hotels and a hundred places to eat are planned.
4 · ⚑ Candour, and a phrase worth keeping
The chief executive said at the 2022 opening: *as a 2030 giga project, we are already opening assets in 2022 — so 2030 is now 2022.* The Library records that as the developer's own claim rather than as a fact, and notes what §22 requires: the great majority of Diriyah is not built. What exists is the cultural core, and this entry describes that. Whether a district can be delivered to 2030 in a fixed vernacular is not yet knowable, and the wider questions about the state financing it are not settled by the quality of the restoration.
