Murabba Palace (Qasr al-Murabba)
Murabba Palace (Qasr al-Murabba), (next to National Museum). (6-9 PM Sun-Fri). This is Riyadh's second old mud-brick palace, built by King Abdul Aziz after he conquered Masmak Fortress because he wanted a more strategically powerful fort. This two-story structure does have an intimidating look and feel to it, but permits are no longer needed to venture inside, where you can find interesting items including the first royal Rolls-Royce. Free.
