Thulaim Palace (Arabic: قصر ثليم) or Thulaim Guesthouse (Arabic: مضيف ثليم), is a double-storey multipurpose historic building in the easternmost extreme of al-Futah, Riyadh, Saudi Arabia, located next to the Batʼha Commercial Center.
Built between 1936 and 1939 by King Abdulaziz ibn Saud on a farm with the same name situated on the edge of Wadi al-Batha in the northeastern fringes of the old city walls, it overlooks the eponymous neighborhood of Thulaim which itself got named after the compound.
[1][2] In 1936, King Abdulaziz purchased a farm called Thulaim, that was located on the northeastern outskirts of the walled town of Riyadh to build a public guesthouse endowed for his father, Abdul Rahman bin Faisal Al Saud.
[3] Initially, the building intended to function as a stopover for travelers coming to Riyadh to meet Abdulaziz and tribal nomads who watered their livestock through a large seven column basin situated in close proximity to it, known as Madi, which is today the site for the Midi Mosque in the National Museum Park.
[4] However, as the smallpox epidemic gripped Arabia in the early 1940s, the building was quickly transformed into a quarantine center and underwent expansion to primarily serve infected patients.
