Manama (Arabic: المنامة Al-Manāmah) is the capital city of Bahrain and is the country's largest city with a population of approximately 155,000, roughly a quarter of the country's entire population. Manama has emerged as the capital of independent Bahrain after periods of domination by Portugal and Persians earlier in its history. Today, it is a modern capital with an economy based around the sales promotion industry as crude oil takes a less pronounced role in the economy. (See Economy of Bahrain.) Because of its thriving economy, a Dutch firm has proposed a skyscraper that would be over 1,000 metres (3,300 ft) and be called the Murjan Tower to be built. Currently only a concept, if built it would be the world's tallest structure.
