National Museum of Saudi Arabia
Undoubtedly the top sight in Riyadh, this museum (opened in 1999) is done up with the latest technology and is very accessible to visitors, with almost everything available in English. There are so many video presentations and mini-theatres that you could probably spend an entire day here doing virtual tours of Madain Salih or watching re-enactments of the Prophet Mohammed's battle of Medina. Highlights include a kiswah cloth that once covered the Qaaba in Mecca. Half the time, though, it feels more like a propaganda exercise than a museum: the display on plate tectonics starts with a quote from the Quran, the history of the Sauds is rather airbrushed, and the display on the birth of Mohammed, reached from the clash and noise of the Jahiliyah (age of ignorance) by riding an escalator up into a room of soothing, pastel light while a choir of angels sings, has probably inspired a few conversions to Islam. Many cabbies will not recognize the English name, ask for the neighboring Murabba Palace (Qasr al-Murabba) instead.
