Montevideo is the capital and largest city of Uruguay. According to the 2011 census, the city proper has a population of 1,319,108 (about one-third of the country's total population) in an area of 201 square kilometres (78 sq mi). The southernmost capital city in the Americas, Montevideo is situated on the southern coast of the country, on the northeastern bank of the Río de la Plata.

The city was established in 1724 by a Spanish soldier, Bruno Mauricio de Zabala, as a strategic move amidst the Spanish-Portuguese dispute over the platine region. It was also under brief British rule in 1807. Montevideo is the seat of the administrative headquarters of Mercosur and ALADI, Latin America’s leading trade blocs, a position that entailed comparisons to the role of Brussels in Europe.

Armação dos Búzios, often referred to as just Búzios, is a resort town and a municipality located in the state of Rio de Janeiro, Brazil. In 2012, its population consisted of 23,463 inhabitants and its area of 69 km². Today, Búzios is a popular getaway from the city and a worldwide tourist site, especially among Brazilians and Argentinians.

In the early 1900s Búzios was an almost unknown village of fishermen. It remained as such until 1964, when the French actress Brigitte Bardot visited Búzios, since then Búzios became popular with the Carioca’s high society, who wanted to escape from the chaotic city life of Rio de Janeiro and enjoy over 23 beaches that the peninsula offers. The city grew to be an international tourist destination.

Today, the peninsula is a travelling site that offers calmness, direct contact with nature and scenic views. The west coast beaches offer calm, clear waters while the east coast ones, facing the open sea, are more wild and draw surfers and water sports enthusiasts. Azeda, Ferradura, João Fernandes and Armação are amongst the most popular beaches in town. At night, Rua das Pedras, Buzios' main street, offers its visitors an active nightlife and a great variety of shopping and restaurants.

Rio de Janeiro is the second-most populous municipality in Brazil and the sixth-most populous in the Americas. The metropolis is anchor to the Rio de Janeiro metropolitan area, the second-most populous metropolitan area in Brazil and sixth-most populous in the Americas. Rio de Janeiro is the capital of the state of Rio de Janeiro, Brazil's third-most populous state. Part of the city has been designated as a World Heritage Site, named "Rio de Janeiro: CariocaLandscapes between the Mountain and the Sea", by UNESCO on 1 July 2012 as a Cultural Landscape.

Founded in 1565 by the Portuguese, the city was initially the seat of the Captaincy of Rio de Janeiro, a domain of the Portuguese Empire. Later, in 1763, it became the capital of the State of Brazil, a state of the Portuguese Empire. In 1808, when the Portuguese Royal Court transferred itself from Portugal to Brazil, Rio de Janeiro became the chosen seat of the court of Queen Maria I of Portugal, who subsequently, in 1815, under the leadership of her son, the Prince Regent, and future King João VI of Portugal, raised Brazil to the dignity of a kingdom, within the United Kingdom of Portugal, Brazil, and Algarves. Rio stayed the capital of the pluricontinental Lusitanian monarchy until 1822, when the War of Brazilian Independence began. This is one of the few instances in history that the capital of a colonising country officially shifted to a city in one of its colonies. Rio de Janeiro subsequently served as the capital of the independent monarchy, the Empire of Brazil, until 1889, and then the capital of a republican Brazil until 1960 when the capital was transferred to Brasília.
