There are several small rock-cut chambers – so called Monte Brasil "Phoenician sanctuaries" – near the beautiful Renaissance town Angra do Heroísmo. Their origin is not entirely clear but some scientists consider that these are burials and temples made by ancient Phoenicians in the 4th century BC – long before the discovery of Azores by Portuguese.

Mount Brasil

Near the center of the beautiful Angra do Heroísmo town is located 205 m tall volcanic cone, rising from the Atlantic ocean. This tuff volcano – Monte Brasil – is connected to the mainland with a narrow isthmus and most of it is covered with forest. Last volcanic activity took place here some 23 thousand years ago.

For several centuries Monte Brasil served as a fortress protecting the town from pirates. Construction of fortifications started in the late 16th century and, as time passed by, the mount was turned into state of art fortress with some 4 km long system of redoubts and several garrisons, as well as a system of roads and pathways to access different parts of peninsula.

Cavities in the rocks

Near the passageway close to Pico of the Zimbreiro – westernmost peak of Mount Brasil in the cliffs are seen several rock-cut chambers facing the ocean.

Chambers are not large – they seem to be not suitable for habitation. But those who made them turned much attention to the water supply. In one chamber is a cistern. Another has a system for gathering and distributing the water to several cavities made on the ground. One cave – with a cistern in it – has a trapezoidal form and an arch-shaped niche in a wall.

Chambers are facing the Atlantic ocean.

These are not the only such chambers – towards the east, near Monte de Facho is located another rock-cut chamber with a ceremonial tank, rock-cut "chairs", cistern and post-holes which testify that a lighter structure was built here as well.

Similar structures have been found on Corvo and other Azorean islands.

Phoenicians from Carthage?

Researchers at Portuguese Association of Archeological Research (APIA) Nuno Ribeiro and Anabela Joaquinito consider that these chambers might be burial sites and shrines made by ancient Phoenicians from Carthage, possibly in the 4th century BC. These chambers could have served as shrines for goddess Tanit – chief goddess of Carthaginians. Some chambers – hypogea – possibly were used as sites for burial. Niches served as shrines and holes and channels for water had ritual meaning.

Theoretically it is possible that Phoenicians reached the Azores – their seafarers managed to cover also bigger distances. Construction of such structures though could mean that these people actually lived in Azores.

More obvious explanations?

Major part of scientific community dismisses arguments of Ribeiro and Joaquinito.

Some specialists consider that these structures served for military purposes and were built in the 16th – 17th centuries. This might have some sense regarding the structures on Mount Brasil – but in some other places where such chambers were found, there are no fortifications.

Other specialists consider that these chambers were made for the needs of agriculture – e.g. to provide water for irrigation. Some chambers though are located in places where no agriculture activities have taken place.

Landmarks of Azores

The westernmost part of Europe is not Ireland or continental Portugal. Westernmost are Azorean islands far, far to the west from the mainland Europe.

Modern Europeans reached these islands in medieval times. There are though multiple claims that islands were reached earlier.

There are also impressive natural landmarks, such as countless waterfalls over the cliffs in Flores island and geothermal fields as well as the beautiful landscape of volcanic craters with their deep calderas and lakes.

Rock cut architecture and sculptures

This category includes outstanding rock cut architecture and large rock cut sculptures.

Rock cut architecture is very ancient form of architecture and some of the oldest rock cut structures were tombs and dwellings.

Some three-fourths of the distance between America and Europe there is a group of nine beautiful islands called the Azores which belong to Portugal. Their names are Flores, Corvo, Fayal, Pico, S. Jorge, Graciosa, Terceira, S. Miguel, and Santa Maria. Many people think them to be the mountain peaks of the submerged continent, Atlantis, which long ago was covered by the ocean.
