Palace of the Rock The Dar al-Hajar (Arabic: دار الحجر, `Stone House` or `Rock Palace`) is a former royal palace located in Wadi Dhar about 15 kilometres (9.3 mi) from Sana‘a, Yemen. Built in the 1920s as the summer retreat of Yahya Muhammad Hamid ed-Din, ruler of Yemen from 1904 to 1948, it sits on top of a structure built in 1786 for the scholar al-Imam Mansour. The palace stayed in the royal family until the Yemen revolution of 1962. The palace is now a museum.
