Riyadh

A global city and the capital of Saudi Arabia, Riyadh has a population of just under six million people. Since the oil boom (starting in 1974), the country has been transformed into one of the top 20 richest in the world in terms of GDP. Saudi Arabia has an economy that is heavily reliant on oil and is the largest exporter of petroleum in the world. Along with Russia, the country produces more oil than anywhere else in the world but in recent times the Saudi government has taken steps to diversify the economy and encourage private sector growth across a range of industries.
