Things to Know About Algar do Carvao

Algar is a Portuguese word that means a natural cavity in the earth. It is more vertical in its orientation, like a well, unlike most caves or caverns.

This Portuguese word derives from an Arabic word, al-Gar, which means crease. Another word Carvao means coal in Portuguese. But the Algar do Carvao is not a source of coal.

This word refers to the dark composition of the rocks. Many people knew about this place on the island for a long time. But they failed to explore it because of the depth and lack of ambient light.

It is a vertical place and was hard to explore for this reason. Because of these reasons, the exploration of this place faced delay.

The first descent of this place happened on 26 January 1893. Cândido Corvelo and Luis Sequeira first explored it. They did it with the use of a simple rope.

A man named Didier Couto made the second descent. He produced the first rough map of the interior. His drawing of the map was on visual observation alone.

But the drawing turned out to be so accurate, without any doubt. A group of enthusiasts organized another descent using a chair platform on 18 August 1963.

It was possible to re-examine the observations with the help of portable lighting. It includes the most remote and narrow sections of the cavern.

The site was open to the public in the late 20th century. Access to the site is also possible through the Montanheiros organization.

They are responsible for matters associated with the Algar. The island of Terceira is the site of four large volcanoes.

These are Pico Alto, Santa Bárbara, Guilherme Moniz, and Cinco Picos. They grouped along a basaltic fissure zone.

It transects the island from northwest to southeast. The Algar do Carvão has a connection with the caldera of the Guilherme Moniz volcano.
