Saudi Arabia is a land of deserts, history, and heritage. Across its regions, you will find palaces and fortresses that tell stories of power and culture. Plan a journey through its castles if you want to see more than the modern skyline. Renting a car is the most practical way to explore. Many of these sites are spread out in Riyadh, Tabuk, Najran, and the Eastern Province, so having your own vehicle makes travel easier and efficient.
This guide takes you through the best castles in Saudi Arabia, from ancient Nabatean fortresses to palaces of the Saudi kings. Each place holds centuries of history and offers technical lessons about architecture, defence, and daily life in the past. By the end, you will see why these landmarks are part of the Kingdom’s identity.
Castles and palaces in Saudi Arabia are not just buildings. They are monuments that explain the history of defence, culture, and governance in the Arabian Peninsula. These structures were designed with technical precision, from clay walls that kept interiors cool to watchtowers that offered wide visibility. Over centuries, they became centres of authority, protecting towns and managing trade. Today, they still stand as heritage landmarks, carefully restored for tourism and education.
Many of these castles are linked to the unification of the Kingdom. Palaces once served as administrative hubs during King Abdulaziz's reign. Fortresses were strongholds in regions like Najran, Al-Jawf, and Tabuk, guarding borders and pilgrimage routes. Restoration projects are ongoing, with the Heritage Commission registering dozens of sites, ensuring preservation under the 2014 Law of Antiquities, Museums, and Urban Heritage.
By exploring these castles, you discover the blend of Islamic, Ottoman, Persian, and local Najdi stles. Thick walls, pointed arches, and courtyards reveal how architecture adapted to harsh climates and social needs. These historical castles in Saudi Arabia are proof of resilience, built to last through wars and centuries.
Saudi Arabia has many castles that show how different regions defended themselves and grew over centuries. Each site was built with a strategic purpose, often placed near trade routes, oases, or city centres. Materials such as mudbrick, stone, and adobe were chosen for strength and insulation. These structures often included watchtowers, courtyards, and mosques, making them military and community spaces.
Masmak Castle is one of the most famous landmarks in Riyadh. Built in the 19th century, it became central to the Kingdom's history when Abdulaziz Ibn Saud captured it in 1902. This event marked the beginning of Saudi Arabia's unification. The castle is built mainly of mud bricks and features thick walls that protect against heat and invasion. Its tall watchtowers rise above the city, while a large inner courtyard connects reception halls and storage rooms.
The castle’s massive doors are strengthened with iron nails, a detail typical of Najdi design. Masmak Castle is preserved as a historical site where visitors can learn about Riyadh’s past. Walking through its courtyard, towers, and decorated gates gives you a clear sense of how the fortress once operated.
Marid Castle, also known as Qasr Marid, is one of the oldest and most important fortresses in Saudi Arabia. Located in Dumat Al-Jandal in the Al-Jawf region, about 50 kilometres from Sakaka, it dates back to the 1st century AD and may even be older. Archaeological evidence confirms its Nabatean origins, a rare example of ancient defensive architecture in the Arabian Peninsula. The castle is famous for the event in the 3rd century AD when Queen Zenobia of Palmyra attempted to conquer it but failed.
The structure has changed shape over the centuries, from a rectangular design to the oval form seen today. It has four towers, each 12 metres high, two main entrances, and a long spiral stairway with about 1,000 steps leading to the top. Built mainly of limestone, the lower floor is in stone, while the upper is in clay. Inside, there are rooms, two wells, and walls with openings for surveillance. Excavations have uncovered Nabatean and Roman pottery.
In modern times, the castle has been restored several times. It has stabilised its mosque and neighbourhood walls, while a broader project added facilities like a café and traditional restaurant. Marid Castle is managed by the Saudi Commission for Tourism and National Heritage.
Tarout Castle is located on Tarout Island in Al-Qatif Governorate, within the Eastern Province. Built on a hill overlooking the old neighbourhood of Al-Dirah, it is one of the most historic sites in the Kingdom. The area around the castle has revealed artefacts dating back over 4,300 years BCE, showing that the site was linked to many ancient civilisations, including the Ubaid, Barbar, and Dilmun.
It originally had four towers, though some collapsed during battles or natural wear. The walls, between four and six metres high and thickened over time, give it a distinctive crab-like shape when seen from above. Tarout Castle is also tied to religious and cultural heritage. Archaeological finds, including statues and inscriptions, suggest it may have been built on a temple dedicated to Ishtar, the Mesopotamian goddess of love and beauty. Additional towers outside the main fort, such as the Tower of Bayt Qais and the Tower of Ibn Dubais.
Tabuk Archaeological Castle is one of the most important historical landmarks in northern Saudi Arabia. Built in 1559, it lies on the ancient road linking Damascus and Madinah.

The structure consists of two floors around an open courtyard. On the ground level, visitors will find a mosque, a well, and several rooms. An internal staircase leads to the second floor, and the towers are used for guarding and observation. At the southwest corner is Ain Al-Sukkar, the natural spring that provided fresh water.
Over the centuries, the castle has been restored many times. Today, it functions as a heritage attraction, housing exhibits of inscriptions, photographs, and artefacts that explain the region’s history. There is also a hall for showing documentary films about Tabuk’s past.

Al-Muwaylih Castle is one of the largest fortresses in Saudi Arabia. Built in 1560, it served as a key station on the Egyptian Hajj Route and became one of the main resting places for pilgrims travelling across the Tabuk Province.
The castle’s design is impressive in scale. Its irregular rectangular layout measures more than one hundred metres on each side, with the northern wall stretching 109 metres. A massive circular tower rises at each corner, built for observation and protection. Two smaller towers strengthen the outer wall, while numerous loopholes along the walls provide guards with clear lines of defence.

One well sits in the courtyard, while the others are in the nearby valley.
Al-Qashla Castle is a heritage landmark in the city of Ha’il. It was built during the reign of King Abdulaziz in 1360 AH (1941 CE). The castle exemplifies the traditional Najdi architectural stle, showcasing how builders used clay and stone. It represents Ha’il’s urban legacy.
The structure is notable for its tall cylindrical towers, which reach about 12 metres high. Four of these towers, known as Al-Sandah towers, reinforce its defensive strength. The castle contains two large gates, a mosque, and multiple rooms that once served administrative and military functions. Visitors will notice colourful wall plaster decorations, with geometric and floral motifs carved into plaster and wood. Even the doors and windows are engraved.

Constructed from mud, clay, and stone, they included large gates, decorated interiors, and courtyards for official and family use.

Ibrahim Palace in the historic city of Al-Ahsa is a striking example of Islamic and Ottoman architectural influence in Saudi Arabia.

Its walls are thick and strong, while the interiors were designed with large halls for official gatherings and guests' receptions. The palace grounds include gardens and auxiliary buildings.
Al-Murabba Palace is one of Riyadh’s most famous heritage sites, built in 1937 by King Abdulaziz. The palace was constructed outside the old city walls of Riyadh to serve as a royal residence and administrative hub, reflecting the rapid expansion of the capital during that time. It stands today as a reminder of the Kingdom’s transition into a new era of governance.
The palace was built using traditional Najdi materials such as mudbrick, limestone, and palm trunks. Its layout includes spacious courtyards, wide rooms, and shaded corridors.
