Sơn Đoòng Cave, considered the largest in the world, was honored by Google on Thursday (14) with the award doodle. The illustration displayed on the search engine’s homepage celebrates the thirteenth anniversary of the site, which was officially discovered on the same date, in 2009. The cave is located in Vietnam, has a size of more than 3.8 million square meters and has been declared a World Heritage Site by UNESCO.

A Google estimate shows an illustration of the cave interior in shades of green, with an explorer observing the space and lit by the rays of light that make up the company’s name. The design is shown in Brazil, Vietnam, and countries such as Argentina, Chile, Mexico, Thailand, Sweden, and the United Kingdom. It is possible to see doodles in search engine versions for computers and mobile phones running Android and iPhone (iOS).

According to Google, geologists estimate that Son Doong Cave formed between two and five million years ago. However, the space was not accidentally discovered until 1990 by local farmer Ho Khanh. In 2009, the man visited the cave accompanied by speleologists Howard and Deb Limbert, speleologists from the British Speleological Research Society, a British organization dedicated to the subject. They were the ones who concluded that this was the largest cave on the planet.
The cave is located near the border of Laos in central Vietnam, and its name means “mountain river” in Vietnamese. Son Doong’s interior space has the ability, relatively speaking, to accommodate a block of 40-storey buildings or to fly a Boeing 747 freely without touching the rock walls.
Within space, scientists have found various geological formations, including the world’s largest limestone pearls and the tallest stalagmites on the planet. Giant holes deep inside the cave allow sunlight and rain to sustain two pristine forest ecosystems, which feed flying foxes, eyeless white fish and the only underground monkeys. One of the forests even has its own climate system.
Son Doong Cave is open to tourists, but it is necessary to obtain specific permits from the local authorities. Visits take place between January and August, due to weather conditions, making access inaccessible at other times of the year. The first guided tours of the place cost about 3 thousand US dollars (about 14 thousand Brazilian reals, in direct transfer). Before the pandemic, there was a year-long waiting list to get to know the place.
