In Austrian Souterrains with Josef Weichenberger


illustration

Most recently, we had the pleasure to visit some Austrian Souterrains guided by our friend and colleague Josef Weichenberger who has been studying these cavities for 40 years. In Austria as in Bavaria, the specific and ancient name Erdstall is used to designate these Souterrains that were for the most part functioning as refuges. These cavities are characterized by their small dimensions: they feature very narrow creep-holes that lead to small rooms with seat-niches for refugees.

 

During this trip, Martin Fickert made a little film inside the underground refuge of Unterstetten in Upper Austria. This video allows perceiving the extreme smallness of these cavities.

Subterranean Worlds Exhibition in Louvre Lens Museum

What is happening underground? What do these worlds that have been firing our imaginations since the dawn of time look like?

Veering between the ideas of death and fertility, ignorance and knowledge, our relationship to subterranean worlds has evolved throughout the history of civilisation and from one artistic current to the next, reflecting developments in our societies above ground. Like an inverted mirror, these realms are the province of things we hide and things we bury, things we fear and things we love, things we do not know and things we can foresee, things we are repelled by and things that inspire us. Their legends and myths, as well as their realities and riches, embody the various contradictions of the human soul.

Featuring more than 200 works, this exhibition, in which the arts from every period dialogue with each other, reveals the full extent of the ambivalence and the fertility of these worlds.

 

 

 

On the occasion of this exhibition Subterranean Worlds, we are very pleased to present four of ours photographs; four pictures of underground refuges (souterrains-refuges) in France, Ireland and Benin.

Looking for souterrains in France and elsewhere in the world, we discovered the diversity and the beauty of this unusual heritage. We are convinced that the diggers of these cavities took pleasure in expressing themselves in the three dimensions of the rock mass and were concerned about the beauty of their work. From the beginning we appreciated the aesthetic dimension of this rock cut architecture and we sought to transmit this emotion through our photographs. We are delighted to share with the Louvre Lens visitors our view of these exceptional monuments.

 We will take part in the au 45th congress of the Société Française d’Étude des Souterrains (French Society for Souterrains Studies) which will be held in Chinon (Indre-et-Loire, France) on 9-11 June 2023. On Sunday 11 June, we will give a lecture: The Souterrains of the Kingdom of Dahomey. 

 

This presentation in Chinon about African Souterrains will be dedicated to the memory of Professor Raymond Mauny, an eminent specialist of West Africa archaeology and history and also the founding president of the French Society for Souterrains Studies.

 
 
In Benin, country of West Africa, around the historic city of Abomey, large areas comprise numerous circular holes piercing the lateritic crust and forming real well fields. Each of these holes is the opening of a vertical shaft which gives access to one or several rooms dug below. The first cavities were accidentally discovered in 1998, during the construction of a road. Professor Klavs Randsborg and his Beninese-Danish team conducted many archaeological prospections and excavations campaigns in the cavities located around Abomey. Thanks to these investigations, they have dated the souterrains to the period of the Kingdom of Dahomey (17th-19th centuries) and they have attributed a defensive function to most of them. These cavities are a special type of refuges souterrains (underground refuges) organized around an access shaft. They are independent but grouped in high density clusters which cover very large surfaces. According to tradition, they had a military function, and their names in the Fon language confirm that. The souterrains took part in the violent history of the Kingdom of Dahomey and its neighbours, during continuous conflicts and razzias conducted to seize goods and slaves. Two study tours, one with Inga Merkyte and Søren Albek, collaborators of the late Klavs Randsborg, allow us to better understand the architecture and the defensive organization of these underground complexes.

Souterrains, known for unexpectedly appearing due to collapse, are also witnesses to a distant past. These are not simple cellars or large extraction galleries, but a category of cavities quite apart. Today there are at least 1,600 of them among thousands of others, not yet discovered or disappeared forever. In the middle of the 18th century, these unusual underground structures aroused the curiosity of some scientists. From the following century, a handful of scholars show that most of them are in fact underground shelters dug by rural populations to protect themselves during times of insecurity. Some of these pioneers insist on the ingenuity of their designers and wonder at the quality of this rock-cut architecture. But, nearly two hundred years later, underground refuges remain unknown, as if these exceptional monuments suffer from their first quality: discretion.

 

After years of visiting, studying and comparing them in different French regions and in other countries, Jérôme and Laurent Triolet devoted a first global study of underground refuges in 1995. Since this work, the literature relating to souterrains has been considerably enriched. With the contribution of new old texts, regional syntheses, monographs, exchanges with other researchers and numerous excavation reports, they are now addressing the issue of underground refuges in France in greater depth, with a better overview of the phenomenon and new questions. Taking an interest in underground refuges in the world also leads to consider those existing in France as the expression of an even more widespread phenomenon, which concerns various periods and continents. This new work helps to better measure the heritage value of these hidden monuments.

Just published: Underground refuges and “Underground Cities” in France and Cappadocia (Turkey)

 This article published in German, English, French and Czech in the new version of the German journal Der Erdstall is the lecture presented at the Second International Troglodytic Architecture Conference in Iran organised by The Research Institute for Cultural Heritage and Tourism and held in Tehran (Iran) on 7 and 8 October 2015.

 

The underground refuges consist of rooms connected by corridors; they are equipped with vital facilities and defence systems. The underground refuge concept has been developed in several ways and, in some parts of the world, men have made very complex subterranean networks: the “underground cities”. We have studied two examples of “underground cities”: the wide networks that exist in Cappadocia (Turkey) (8th - 15th century), and the large refuges located in Northern France (15th - 18th century). The study of the architectural characteristics and the global organisation of the networks allows to reconstruct the defence and the life inside the cavities. The comparison shows that the existing differences between these two geographical groups of “underground cities” are the result of two kinds of human adaptation in response to the same need.

A new topic in Photo Library: Cave dwellings in Lanzarote (Canary Islands)


illustration

Lanzarote is a black and red land emerging from the waters of the Atlantic, off the Sahara coast. The island is the result of an intense volcanic activity and it is impossible to ignore the presence of the volcanoes which occur everywhere in the landscape. The last volcanic eruption dates from 1824 and the population still remember the terrible history of the Timanfaya eruption that began in 1730 and continued for more than 2000 days, covering about one third of the island surface and radically changing its physiognomy. It is the second largest lava eruption recorded within historic time after the Laki eruption (Iceland). Specific caves - the lava tunnels - are dispersed in this volcanic landscape. If the magma is fluid enough, it flows quickly and it cools and solidifies only as it comes into contact with the outside. The lava crystallizes on the edges of the flow, developing a hard crust whereas the lava is still liquid in the center. When the lava flow has ceased, the solidified walls delimit a lava tube, that is, a tube surrounding a large or small central cavity. When the artist César Manrique returned to Lanzarote in 1968, he incorporated other kind of lava caves in the building of his home and studio. He thus created an absolutely unique rock cut house. This prolific artist, who established through his work a veritable dialog with nature and landscapes, devised also a vast house dug into a cliff.

 

 

 


 

A new topic in Photo Library: Journey to the Center of the Earth (Iceland)


illustration

The famous Journey to the Center of the Earth imagined by Jules Verne begins in Iceland within the Snæfellsjökull crater. It is an encrypted message from a 16th-century Icelandic alchemist that shows the way : “Descend, bold traveller, into the crater of the jokul of Sneffels, which the shadow of Scartaris touches before the kalends of July, and you will attain the centre of the earth; which I have done, Arne Saknussemm.” Once arrived at the top of the volcano, Professor Lidenbrock, his nephew Axel and their Icelandic guide enter the central chimney determined to reach the centre of the earth. After a long journey throughout the underground world, the three explorers go out at the other end of Europe, in a chimney of the erupting Stromboli. While the adventure takes place in natural and volcanic caves, with the Journey to the Center of the Earth, Jules Verne perpetuates the myth of long distance tunnel, a myth that is always very present in contemporary collective imagination.  

 

 


 

New topic in the Photo Library: Souterrains and caves in Benin


illustration

Benin, this small country of West Africa with a rich history, has an exceptional underground heritage. In the South of the country, around the historic city of Abomey, former capital of the Kingdom of Dahomey, there are innumerable souterrains-refuges (underground refuges) of a special type. These cavities have been revealed in 1998 by Professor Klavs Randsborg and his Beninese-Danish team. The density of these souterrains is very impressive: more than 1000 cavities have been listed in this region. In the North of the country, natural caves and rock shelters have been used as refuges or places of worship; traditional ceremonies are still taking place in some of them.

 

 

Souterrains around Abomey

Around the former capital of the Kingdom of Dahomey, large areas comprise numerous circular holes piercing the lateritic crust and forming real well fields. Each of these holes is the opening of a vertical shaft which gives access to one or several rooms dug below. The first cavities were accidentally discovered in 1998, during the construction of a road in Bohicon. Professor Klavs Randsborg and his Beninese-Danish team conducted many archaeological prospections and excavations campaigns in the souterrains of Bohicon and in many other cavities located around Abomey. Thanks to these investigations, they have dated the souterrains to the period of the Kingdom of Dahomey and they have attributed a defensive function to most of them. In fact, these cavities are a special type of souterrains-refuges (underground refuges) organized around an access shaft. They are independent but grouped in high density clusters which cover very large surfaces and certainly could shelter all the local population. The souterrains were part of the violent history of the Kingdom of Dahomey and its neighbours, a history of ongoing conflicts and razzias conducted to seize goods and slaves. In 2014, a study tour led us to understand the scale of the phenomenon. At present, we are working with Inga Merkyte and Søren Albek, collaborators of the late Klavs Randsborg, with the aim of better understanding the architecture and the defensive organization of these underground complexes.

Caves in Northern Benin

In the North of Benin, in Donga and especially in Atakora, the nature has carved rock shelters and deep caves in the cliffs. The inhabitants of surrounding villages used these cavities to hide from enemies during local conflicts and also to escape the French army during the colonial period; additionally, they concealed their reserves inside big silos made of crude earth. Some of the caves are also sacred sites and they are still accommodating fetishes and religious ceremonies.

New topic in the Photo Library: Tropical troglophiles


illustration

In the intertropical zone, subterranean environment is still characterized by its stability and it preserves from extreme heat. It also protects from the drying effects of sun rays and provides a habitat constantly saturated with humidity which is much sought after by some species. Numerous invertebrates, which are troglophile, can spend their entire biological cycle inside the cavities, other, which are subtroglophile, take shelter only temporarily under the ground. Like in aboveground habitat, biodiversity increases significantly around the equator and the size of arthropods is impressive.
