Al-Hukm Palace (Arabic: قصر الØكم, romanized: Qaá¹£r al-Ḥukm, lit. 'Governance Palace'), also known as the al-ʽAdl Palace (Arabic: قصر العدل, romanized: Qaá¹£r al-Ê¿Adl, lit. 'Justice Palace'), so called from the public square it overlooks from the south,[1] is a historic palace and a popular cultural heritage landmark in the ad-Dirah neighbourhood of Riyadh, Saudi Arabia, located directly opposite to Imam Turki bin Abdullah Grand Mosque in the Qasr al-Hukm District. It is the official site where tribal leaders and members of the Saudi royal family pledge allegiance to the country's political leadership.[2][3][4] It was known as Ibn Dawwas Palace[5] until the 1820s when Turki bin Abdullah, after gaining control of Najd, shifted the royal family's center of power from Diriyah to the walled town of Riyadh as a result of the former's severe dilapidation in a brutal siege during the Ottoman–Wahhabi War of 1818.
