13. Tuwaiq Palace
Recipient of the Aga Khan Award for Architecture, 1998. 

14. Tuwaiq Palace
enclosed by inclined curved walls, forming a sinuous curvilinear spine 800 m long, 12 m high, and 7-13 m wide, used for guest services and accommodations
outdoor sports facilities, gardens, and extensive landscaping laid out in a pattern of complementary spirals, circles, and curves, in harmony with the building's undulations

15. Mushrooming from the spine are tents supported by tensile-structure technology
design makes reference to two local archetypes - the fortress and the tent

16. The tents enclose the large-scale spaces: main lounges, reception areas, multi-purpose halls, restaurants, and a café
 dramatic contrast between the lush greenery of the outdoor spaces enclosed by the spine and the arid rocky plateau beyond its walls
The white tents are made of Teflon-coated, woven fibre fabric
 The tents are enclosed by glass walls
