9 interesting facts about Rio de Janeiro

1. Mistaken identity leads to a name

Imagine sailing into Guanabara Bay, thinking you've found the mouth of a massive river. That's what happened to Portuguese explorers in January 1502, and thus they named this marvel Rio de Janeiro, which translates literally to "January River". But it's not a river at all; it’s an enormous bay surrounded by more than one hundred islands that dot its waters like jewels.

So yes, a misunderstanding birthed the moniker for this bustling metropolis. Though the bay defied the explorers' initial anticipations, it has since morphed into a quintessential element of Rio's vista, presenting awe-inspiring panoramas.

2. More than one hundred islands

Now that you know of Guanabara Bay, you should also know it isn't just a pretty face in Rio's panoramic vistas; it's an ecological treasure trove with more than one hundred islands each telling its own unique story.

From tiny uninhabited islets that provide sanctuary for birds and sea turtles to larger inhabited ones with their own communities, these islands reflect the rich ecological tapestry of Rio de Janeiro.

Beyond their natural beauty, some of these islands have stories deeply intertwined with Brazil’s history. Exploring them offers a glimpse into the past and present struggles over environmental conservation and urban expansion.

Among this archipelago, certain names stand out due to their significant contributions either ecologically or historically. For instance, charming Paquetá Island takes you back in time with its car-free streets lined by flamboyant trees while Fundão Island hosts leading research institutions studying marine biology among other sciences.

3. Floresta da Tijuca: the lungs of Rio

Speaking of nature, it’s time to step into Floresta da Tijuca, the world's largest urban forest tucked within city limits—a true testament to nature’s resilience. Once devastated by coffee plantations, this rainforest was replanted in the 1800s to protect Rio’s water supply, making it today home to hundreds of species and fresh air galore.

With an impressive 32 square kilometers, this green giant not only steals your breath with its views but also with its biological diversity.

The lush expanses are crisscrossed with hiking trails leading adventurers past waterfalls, caves, and some stunning viewpoints where vistas stretch out over sea and city alike.

It stands as proof that when we let nature thrive even amidst urban sprawl incredible things can happen—the green heart beating strong within Brazil's marvelous city.

4. One of the 7 New Wonders of the World

As you see, Rio boasts numerous natural wonders that could grace any postcard, but its most renowned landmark isn't just a product of nature.

Voted one of the 7 New Wonders of the World in 2007, alongside iconic structures like the Colosseum in Rome and the Taj Mahal in India, the statue of Christ the Redeemer stands as a testament to human ingenuity.

This magnificent statue, with its outstretched arms spanning 28 meters, defied traditional construction methods. Erected atop Corcovado Mountain, there was barely enough space to accommodate scaffolding during its creation.

And Christ the Redeemer isn’t merely a statue; it's a monumental symbol of divine protection over Rio de Janeiro.

Perched atop Corcovado Hill, standing 709 meters above sea level, this 30-meter-high marvel is both the pinnacle and the most coveted destination for tourists in Rio de Janeiro.

5. Carnival party like no other

Imagine a party so vast it earns the title of the biggest carnival party in the world. That's Rio for you, as designated by Guinness World Records. Here, the streets burst into an explosion of colors, music, and dance every year.

It's not just about feathered costumes or mesmerizing parades; it’s a celebration deep-rooted in Brazilian culture that brings together communities from all walks of life. Carnival is also very important – and a lot of fun – in other parts of Brazil, such as Olinda and Salvador, but Rio catches the eyes of the world.

The magic behind this colossal festivity is partly thanks to numerous “Escolas de Samba” (samba schools) located primarily within favelas. Far beyond mere bands, these academies stand as guardians of tradition, fostering communal bonds via the rhythm of samba. But that’s not all.

Besides the samba schools, street parties known as “blocos” dot every corner of the city, offering everyone a chance to dance and party for free. This grandeur event officially lasts five days but blocos start taking the streets a few months before Carnival itself.

6. The origins of the term “Carioca”

Did you know that those who are born in Rio de Janeiro (the city, which is capital of the state of the same name) are called “cariocas”? The word carioca has Tupi origins, but its exact meaning still generates debate.

The most widespread idea is that it would be the combination of kara’iwa (white man) and oka (house): “white man’s house”.

Another hypothesis says that the name means “house of the pleco fish”. That would be because when the first Europeans arrived on the coast, their armor would have reminded the natives of fish scales.

How these words became the city’s gentile is another story. In the city of Rio, there is the Carioca River, which originates in the Tijuca Forest and passes through neighborhoods such as Cosme Velho and Laranjeiras.

We don’t know which came first: the name of the river or the gentile. Some argue that the “carioca” of the river passed on to those who lived nearby, while others say the opposite. What is known for sure is that in the colonial period, people born in Rio de Janeiro were already known as cariocas.

7. The real name of Copacabana

And speaking of names, one of the most famous beaches in the world, Copacabana didn’t always have this name. Long before it was known as such, the beach and region where it’s located was called Sacopenapã, a name of Tupi origin that was given by fishermen who passed through there.

Over time, a chapel was built in the area with the image of Our Lady of Copacabana, brought by Bolivians. And the origin of the name “Copacabana” comes from the expression kota kahuana, from the Aymara language, which means 'view of the lake'. There is also a Bolivian city with the same name.

8. The bluest skies in the world

Cariocas often boast about their city having one of the most vibrant atmospheres, but did you know that this extends beyond its bustling streets to the very sky itself? In 2006, Rio's sky was considered the most beautiful in the world.

The title was achieved in a competition with 19 other places on six continents. Television producer Anya Hohnbaum, from Scotland, carried out the research by traveling the world for 72 days, after being chosen in a promotion on the website The Blue Sky Explorer.

The scientific part of the research was carried out with the help of the optical radiation team at the National Physical Laboratory (NPL) from London, England.

Every place Anya Honbaum visited went through a battery of tests, which measured aspects such as sky color, clarity, luminosity, and cloud density.

A behavior classification was also made. In the research, the visitors’ reactions were recorded when catching a glimpse of the sky at a given destination. This reaction, normally admiration, was measured and compared in its degrees of intensity.

9. The largest soccer match in the world

Many people associate Brazil to football, so this list of facts about Rio de Janeiro wouldn’t be complete without a mention to this national passion.

Did you know that the Maracanã Stadium in Rio witnessed the football match with the largest audience ever recorded? Yes, we are talking about the legendary match between Brazil and Uruguay in 1950. The FIFA World Cup final attracted an astonishing crowd: officially 199,854 spectators, although some say there were even more.

But the Maracanã goes beyond world records and astronomical figures. This place has witnessed many both sporting glories and disappointments since its inauguration for that same World Cup in 1950 until today.

Although without a doubt its football moments are the main protagonists here, making the stadium a symbol of Brazilian football culture, it has also hosted memorable concerts and other events, thus contributing to the country’s popular culture outside of strictly sports.

Another curious fact is that the word “maracanã”, in Tupi, means “maracá” (rattle) and “nã” (similar). The term designates the sound emitted by the Maracanã-guaçu, a bird common in the region from the Amazon to Bahia which makes a noise similar to a rattle. Before the construction of the stadium, there were many these birds on site.

Regardless of whether you are an avid soccer fan or simply enjoy visiting iconic places steeped in history during your travels, a visit to the Maracanã is guaranteed to be memorable.
