National Museum in Riyadh

As usual, trying to find anything in Riyadh is virtually impossible and nothing on the web helps in any way to find this museum. Also, describing Riyadh as a beautiful city beggars belief. I would love to learn more about Saudi culture, but it must be said that the Saudis have only themselves to blame if no-one visits any so-called places of interest here. A map of the museum's location please.
