Riyadh is the capital of Saudi Arabia and the country’s most populous city, on the Najd plateau in the central Arabian Peninsula.

Where Is Riyadh Located?

Riyadh sits on the Najd plateau at about 600 meters above sea level and is described by Saudi sources as one of the most densely populated capitals in the world relative to its built-up area, covering only about 1% of Riyadh Province’s total land. Its climate is harsh continental desert: summers reach about 48°C, January lows can drop below 10°C, and annual rainfall averages only 84.4 millimeters.^[1]

A Brief History of Riyadh

The site has a long history under different names. Saudi historical sources trace the earliest reference to the area to around 715 BCE, when a settlement called Hajar served as capital of the Yamama region, with archaeological evidence suggesting habitation by the Tasm and Jadis tribes roughly 2,500 years ago. Riyadh itself grew up on the ruins of Hajar, and the name began to be used as a collective term for a cluster of nearby villages from the 17th century onward. In 1748, a mud wall was built that unified the settlement into a single city. The Battle of Yamama in 634 CE is credited with leading the Bani Hanifa tribe to convert to Islam, and the city lies near Diriyah, capital of the First Saudi State.^[1]

The most consequential date in Riyadh’s modern history is 1902, when King Abdulaziz Al Saud entered the city, an event tied closely to the founding of the modern Saudi state and still commemorated at Al-Masmak Palace. Under King Abdulaziz, Riyadh saw its first oil-funded development milestones: a settlement plan for Bedouin communities, the start of oil exports, the opening of the old Riyadh airport, the arrival of electricity, and a railway link to the Eastern Province via Dammam, all within a few decades of the 1902 takeover.^[1][2]

Government and Population

Riyadh is Saudi Arabia’s seat of government, home to government ministries, foreign embassies and international missions, as well as the headquarters of the Gulf Cooperation Council and the Public Investment Fund. The 2022 census counted 7,009,120 residents, with Saudi nationals making up about 64% of the population and non-Saudi residents about 36%; the city’s annual population growth rate runs as high as 4%, well above the 2.11% national rate. Development of the city is overseen by the Royal Commission for Riyadh City, chaired by Crown Prince Mohammed bin Salman, and Riyadh hosted the 2020 G20 Summit.^[1]

What Is Riyadh Known For?

The skyline feature most associated with Riyadh is the Kingdom Centre, a skyscraper inaugurated in 2002 and recognizable for the inverted-arch gap near its top, spanned by a 60-meter steel Sky Bridge that weighs about 300 tonnes. It followed the slightly earlier Al-Faisaliah Tower, the Kingdom’s first skyscraper, inaugurated in 2000 at 267 meters with a glass sphere at its summit. Older landmarks include Al-Masmak Palace, tied to the 1902 capture of the city, and natural features such as Tuwaiq Mountain, which Saudi sources describe as both a geological landmark and a cultural icon of the area. More recently, King Salman Park, still under development in the city center, is planned to become the largest urban park in the world at more than 16 square kilometers once complete.^[1]

Why Riyadh Matters

As the political and administrative center of Saudi Arabia and home to the Public Investment Fund, Riyadh anchors the kingdom’s Vision 2030 economic diversification program, and its population growth and large-scale infrastructure projects, including a new metro system opened in November 2024, reflect a deliberate push to build it into a global capital rather than solely an administrative one.^[1]
