Al Jubail

Al Jubail is a major industrial city and port on Saudi Arabia’s east coast, historically known as a small fishing and pearling village. Its modern transformation began in the 1970s when it was designated as the site for one of the world’s largest industrial complexes, managed by the Saudi Arabian Oil Company (Saudi Aramco) and the Royal Commission for Jubail and Yanbu. Today, it is a global hub for petrochemicals, steel, and fertilizer production, built alongside a modern planned city for its residents.

Al Khobar

Al Khobar is a major port city on Saudi Arabia’s eastern coast, which grew from a small fishing village in the early 20th century into a vital commercial and residential hub. Its modern development is closely tied to the discovery of oil in the region, particularly after the 1930s, when it became a key administrative and logistics center for the Saudi Aramco oil company. Today, it forms part of the larger Dammam metropolitan area and is known for its modern corniche, shopping malls, and as a gateway to nearby Bahrain via the King Fahd Causeway.

Dammam

Dammam is a major port city on Saudi Arabia’s eastern coast and the capital of the Eastern Province. It grew from a small fishing village into a modern metropolis following the discovery of vast oil reserves in the region in the 1930s, which transformed it into a vital commercial and administrative hub for the Saudi oil industry. Today, it forms the core of the Dammam Metropolitan Area, a key economic center alongside the nearby cities of Dhahran and Al Khobar.

Dhahran

Dhahran is a major city in Saudi Arabia’s Eastern Province, historically significant as the site of the first commercial oil discovery in the kingdom in 1938. It grew from a small company town for the Arabian American Oil Company (Aramco) into a modern administrative and residential hub, serving as the headquarters of Saudi Aramco, the world’s largest oil company.

Al Qatif

Al Qatif is a historic oasis region and city located along the eastern coast of Saudi Arabia, on the Arabian Gulf. It is one of the oldest inhabited areas in the Arabian Peninsula, with a history of continuous settlement dating back over 4,000 years, known in antiquity for its prolific date palm groves and as a center for trade and pearl diving. Today, it remains a vital agricultural hub and a significant cultural site for the country’s Shia Muslim community.

Ras Tanura

Ras Tanura is a major oil port and refinery complex located on a peninsula in Saudi Arabia’s Eastern Province. Historically a small fishing village, it was transformed in the 1930s after the discovery of oil, becoming a critical hub for the global energy industry operated by Saudi Aramco. Its name, meaning “cape oven” or “cape brazier” in Arabic, is thought to refer to the area’s historically prominent lighthouse or beacon.

Al Diriyah

Al Diriyah is the historic birthplace of the First Saudi State and the ancestral home of the Saudi royal family. Founded in the 15th century, it served as the capital from 1744 until 1818, when it was destroyed by Ottoman forces. Today, its restored mud-brick ruins in the At-Turaif district are a UNESCO World Heritage Site and a major cultural destination near Riyadh.

Riyadh

Riyadh is the capital and largest city of Saudi Arabia, historically a major settlement on the ancient trade and pilgrimage routes of the Arabian Peninsula. It transformed from a walled oasis town into a modern metropolis after being captured in 1902 by Abdulaziz Al Saud, who used it as the base for founding the modern Kingdom of Saudi Arabia. Today, it serves as the nation’s political, financial, and administrative center, home to landmarks like the Masmak Fortress, which symbolizes its foundational history.
