A Geological Wonder

Algar do Carvão, also known as the Cavern of Coal, is an ancient lava tube or volcanic vent that dates back thousands of years. Situated within the civil parish of Porto Judeu, in the municipality of Angra do Heroísmo, this natural wonder gets its name from its vertical orientation, resembling a well, and the dark composition of its rocks.

Journey into the Depths

As you approach the mouth of Algar do Carvão, you'll be greeted by a 45-meter vertical passage leading to the interior. Descending further, you'll encounter a ramp of debris and gravel, eventually reaching the crystal-clear waters of the interior pool, which can be as deep as 15 meters. It's fascinating to note that the pool is fed by rainwater and can sometimes dry up during the summer months due to limited precipitation.

A Thriving Ecosystem

Algar do Carvão is not only a geological wonder but also a haven for a diverse range of plant and animal species. The mouth of the cavern is adorned with a rich tapestry of plants, including various endemic species. Inside, you'll find a fascinating array of invertebrate species, such as the cavernous spider Turinyphia cavernicola and the centipede Lithobius obscurus azorae. The presence of rare moss species, like Alophosia azorica and Calypogeia azorica, adds to the enchanting atmosphere of the cavern.

Historical Significance

Beyond its natural beauty, Algar do Carvão holds historical significance. It is directly associated with the caldera of the Guilherme Moniz volcano, which is part of a volcanic complex that includes Santa Barbara, Pico Alto, and Guilherme Moniz itself. This volcanic complex played a crucial role in shaping the island of Terceira and its unique landscape. Exploring Algar do Carvão allows you to step back in time and witness the powerful forces that shaped the island.
