The contents of this hall help you visualize the long-term vision of sustainable development that King Khalid had for the Kingdom which he displayed through the establishment of various strategic projects across all sectors of social, cultural, economic and infrastructure development. Many of these projects remain amongst the leading achievements in Saudi Arabia. In addition, there is a model of the Ka'aba door, which was commissioned by King Khalid. The door was made of pure gold and is a unique masterpiece which is his most visible legacy to the Two Holy Mosques.
