Riyadh is the political and commercial centre. The grain is wide roads, wadis, and a few surviving mud-brick compounds. Diriyah sits next door and has its own page. Stay here for the capital as people actually use it.

Masmak and the museum
Qasr al-Masmak, قصر المصمك, is a clay fort from the 19th century. It sits in what used to be the whole town. The National Museum is in the King Abdulaziz Historical Centre, a short walk from that older grain. The collection is the country's own timeline. Nabataean and South Arabian inscriptions sit under the same roof as later rooms.

Wadi Hanifa and the Boulevard
Wadi Hanifa, وادي حنيفة, is the city's long green cut. Parks, a lake, and a path follow the old watercourse. The Boulevard is a seasonal pedestrian strip, not a street you live on. Both tell you the same thing. Riyadh is not only towers.


Heat
Summer days are hot and dry. Shade is a plan, not a mood. Winter evenings can be cool enough for a jacket. Rain is rare and then sudden. Indoor life is the default from late morning until the sun drops.
