There are 10,150 documented monuments and about a dozen museums in Sa'udi Arabia. The National Museum, originally opened at Riyadh in 1978, focuses on archaeology and ethnography. Major renovations were completed in 1999. Many of the other historic and cultural sites are religious in nature and the high figures for attendance reflect the huge numbers of Muslim pilgrims who visit the kingdom each year. Riyadh is also home to a local museum, an archaeological museum at King Sa'ud University, and a geological museum.
