Al Maryah Island

Al Maryah Island (Arabic: جزيرة المارية) is designated as the Central Business District of Abu Dhabi, the capital of the United Arab Emirates. Previously named Sowwah Island, it is a natural island located northeast of the Abu Dhabi Island, and west of Reem Island. It is managed by the Mubadala Investment Company as well as Aldar, and serves as the home of the Abu Dhabi Global Market (ADGM), an international financial free-zone operating under English Common Law.

Positioning itself as the 'Capital of Capital', Al Maryah Island is a mixed-use development zone comprising grade A commercial offices, luxury retail and hospitality, and specialised healthcare facilities. It is the regional base for many multi-national financial institutions such as J.P Morgan, Morgan Stanley, Goldman Sachs, and "new private equity" such as BlackRock and Brevan Howard. It is also home to The Galleria, one of Abu Dhabi's largest luxury retail complexes; Cleveland Clinic Abu Dhabi, a multi-specialty hospital; and two 5-star hotels, namely the Rosewood Hotel and the Four Seasons Hotel. The island also features multiple apartment residences.

Announced in December 2025 through a joint venture by Aldar and Mubadala, the northern side of Al Maryah Island is earmarked for a massive expansion of office, residential and retail space, doubling the available office space on the island, along with 3000 luxury waterfront apartments, as well as a landmark hotel.
