Dubai  is the most populous city and is one of the seven emirates of the United Arab Emirates (UAE). It is located south of the Persian Gulf on the Arabian Peninsula and has the largest population with the second-largest land territory by area of all the emirates, after Abu Dhabi. Dubai and Abu Dhabi are the only two emirates to have veto power over critical matters of national importance in the country's legislature. It is rather like an independent city-state and is the most modern and progressive emirate in the UAE, developing at an unbelievable pace in the tourist and trade sectors especially. Recently Dubai won the bid to host EXPO 2020, a Universal scale Registered Exposition approved by the Bureau of International Expositions (BIE), Paris.

Abu Dhabi, the capital and the second largest city in the United Arab Emirates, lies on a T-shaped island jutting into the Persian Gulf from the central western coast. The city is also one of the most modern cities in the world. Abu Dhabi features large gardens and parks, green boulevards lining all the streets and roads, sophisticated high-rise buildings, international luxury hotel chains and opulent shopping malls.

Barcelona – Spain's enchanting capital, second largest and most populous city. It is a huge city that vibrates with life, and there’s certainly not another city in the country to touch it for its sheer style, looks or energy. It is one of the world's leading tourist, economic, trade fair and cultural centers, and its influence in commerce, education, entertainment, media, fashion, science, and the arts all contribute to its status as one of the world's major global cities. Barcelona is home to masterpieces of many great architects – the most famous of which is Antoni Gaudí.
