I visited this library several times and it was the highlight of my stay in Riyadh.
The King Fahd National Library (KFNL, Arabic: مكتبة الملك فهد الوطنية) is the legal deposit and copyright library for Saudi Arabia. KFNL was established in 1983 in response to an initiative made by the people of Riyadh when King Fahd ascended the throne. The project was announced in 1983 and the implementation started in 1986. Now to this day, the library is known for its sustainability and up-to-date energy concepts.
