Riyadh:Royal palaces in Saudi Arabia have been central to the country's state administration, diplomacy, and royal life, reflecting a progression from traditional mud-brick architecture to the use of reinforced concrete. These developments are detailed in the National Day historical guide by the King Abdulaziz Foundation for Research and Archives (Darah).

According to Saudi Press Agency, the history of royal palaces begins with Qasr Al-Hukm in Riyadh, established in 1824 by Imam Turki bin Abdullah. The palace was later fortified and expanded by Imam Faisal bin Turki, featuring a connecting bridge to the Imam Turki bin Abdullah Grand Mosque. After reclaiming Riyadh in 1902, King Abdulaziz reconstructed the palace into a comprehensive administrative and residential hub, incorporating the Royal Court and other essential facilities.

In 1936, King Abdulaziz ordered the construction of Al-Murabba Palace near Riyadh's city walls. Completed in 1938, it was designed in the Najdi style with traditional materials and served as the Royal Courts operational base, welcoming foreign dignitaries and issuing significant state decisions.

Advancements in architecture were evident with the creation of Al-Hamra Palace in 1942, noted for its early use of reinforced concrete and distinctive red facades. Initially linked to Crown Prince Saud bin Abdulaziz, it later became the Royal Court during his rule and hosted visiting state leaders.

Al-Nasiriyah Palace in Riyadh, initiated by King Abdulaziz and rebuilt under King Saud, functioned as a royal residence and Royal Court. It was renowned for its expansive gardens, fountains, and grand architectural features.

In Jeddah, Khuzam Palace, commissioned in 1928 and completed in 1932, was built with limestone, cement, and wood. It served as a venue for significant international treaties before transforming into a museum.

These palaces remain as enduring symbols of Saudi Arabias political, diplomatic, and architectural heritage, as emphasized in the National Day guide.
