With a population of 2 million, surrounded by tropical rain forest and located 1,300 kilometers from the Atlantic ocean, the urban sprawl of Manaus is a major tourist destination in Brazil.
While the city might not be a household name just yet, it has certainly been in the spotlight this summer, as one of the host cities of Brazil's World Cup soccer tournament.
But as the city showed off its state-of-the-art developments to the world, it also become a focal point for the controversy surrounding this year's World Cup. Questions have arisen on how the host cities will use the new stadiums and infrastructure with the tournament now packed up and moved on.
Located on the main road to the airport in Manaus, the Arena da Amazonia is a brand new stadium designed by Germany's GMP Architects. It has a roof that is designed to be "climate appropriate" by providing natural shading and make effective use of daylight, and its toilets flush with rainwater collected from it.
The stadium will also form part of a new multi-use sports park which houses field and track facilities, an aquatics center and an arena for the Brazilian dance of Samba – known as the "Sambadrome".
But despite all this, the stadium became one of the more divisive symbols of the World Cup - a tournament that was played out against a background noise of disgruntled masses who were angry over the billions spent on the event.
Three workers died during the construction of the stadium, which only had four matches played in its grounds. Materials had to be shipped all the way from Europe to construct it, and the pitch was reportedly sprayed green to mask its poor condition ahead of the match between Italy and England.
But there are wider criticisms that could have more serious implications for the city.
Promised infrastructure projects – such as a state-of-the-art monorail - have so far failed to materialize, for example. There are also concerns over the stadium's legacy and local soccer team Fast Clube's ability to fill its 44,400 seats. HBO presenter John Oliver described it as having the potential to be the "world's most expensive bird toilet".
Architect Hubert Nienhoff, CEO and partner at GMP, defended the stadium calling it a "characteristic landmark" that signifies the careful use of natural resources in the region.
