While the majority of Corfu’s visitors look up at the sunny sky and look out over the blue sea or at the lovely architecture in Corfu Town, something is happening underground that very few are aware of. Caves! The island has more than 213 of them, of which 89 are ‘under study’ by Dutch speleologist René van Vliet. He searches, explores, photographs and describes the underground treasures and shares his experiences with the Corfiots and the general public. He often writes articles about the caves of Corfu and their stories for Greek newspapers, magazines and news sites (in 2019: 85 publications). His articles are also published in Athens and by the National Herald in New York.
Besides sea caves and a waterfall cave, Corfu has land caves in various shapes and formats. Some are like holes, big and small. In Greek they are called spilies, in Corfiot dialect: graves. Deep openings in rocky terrain are known as varathra. Also sinkholes katavothres can be found on Corfu. Some caves have been in use through the ages for practical purposes as storing milk and vegetables, thanks to their constant temperature and darkness. The locals would call these kaves. A number of caves were lived in during the Palaeolithic Age and Neolithic period, or provided shelter against pirates, like the impressive Katsouris cave in Glyfa, or against Italian and German bombing during World War II.
The folklore, oral tradition and the personal stories about the caves are the favourite subject of the Dutch speleologist. He studies old Greek literature, analyses old maps and talks to villagers, shepherds and foresters. Researching caves in Corfu is not an easy task. Many caves are hidden, some already for many decades like for example the Panadograva cave in Sgourades. For generations stories had been told about this cave, until René proved it was not a legend but just deeply hidden in the forest. It took him three years to find it, but with the help of the chairman of the village and a local guide, the speleologist could visit the cave during his summer expedition.
While talking, René van Vliet receives a message from a Greek friend that a cave with a unique history has been found. The news clearly excites him. He says: “This cave was hidden for decades and is of great historical value to the local community. I heard that there were lots of bats in the cave. I can’t wait to explore the cave and to see the flora and fauna!”
As mentioned above, (at least) 89 caves are still waiting for a visit. To find and explore those caves many Corfiots help René van Vliet to clear dense vegetation or to guide him through forests or on heights. Only with the local help Corfu’s hidden caves can be discovered or rediscovered. After visiting a cave, often aided by special equipment, the speleologist shares his information, pictures and videos through his website www.speleocorfu.com. Thus also serving archaeologists, geologists and biologists. René van Vliet is always available for lectures about his research and the hidden natural beauties on the island of Corfu.
Man with a mission…
In April and August-September 2019 René van Vliet was out again exploring caves in Corfu. He calls speleology his hobby, but he is clearly a man with a mission. He wants to mark out all the caves on the island, record their beauty and history and preserve this valuable information for future generations. What’s more, he reckons there are still hidden caves to explore, time capsules with traces from Corfu civilisations from thousands of years ago, untouched and with valuable information.
When I ask him about his goals for the long term he promptly answered: “Keeping the vulnerable caves with their unique flora and fauna clean, to make and keep them accessible, and to inform the younger generations about the treasures of their island.” These places with a long history must be passed on in good condition to the next generations!
Recent discovery in Spartilas
René van Vliet’s lively enthusiasm clearly shows in the article in Corfu Magazine, issue 23 (October 2019) in which he described the various caves he visited this year, standing out by their natural beauty. Amongst them is the Platesgourna cave in Spartilas, discovered by Nikos Gisdakis in the winter of 2018.
René went up to northern Spartilas to visit this cave for the first time in April: “The Platesgourna cave is hidden in an olive grove and has two small entrances. (…) After a small hall follows the first chamber, with stunning beauty.” (see the main picture above this article). In August, the speleologist visited the cave for the second time and this time with special lamps so he could map and photograph the cave. A few days later he visited the Platesgourna cave for the third time. “I was in the upper level of the cave and suddenly I saw an open space. Behind a big monolith and beneath the first chamber there is a second chamber with stalactites hanging from the ceiling and a group of four stalagmites, the tallest about 1,5 metres high! (…) I would not be surprised if there is also a third chamber.”
Unfortunately the speleologist could not go further down, because he lacked a vital piece of equipment, a drill. During a next expedition he will continue his exploration of the Platesgourna cave.
Support the important research of the caves!
Sponsorship is very important for the research of the caves of Corfu. The two caving expeditions this year were materially supported by companies from The Netherlands (CanyonZone), France (Aventure Verticale), Spain (Rodcle), Italy (Climbing Technology), Greece (Vasilikos / Nitecore). Fresh- All Day Food Bar in Gouvia offered the speleologist to support his next caving expedition. René van Vliet hopes that travel organisations, hotels and car rentals will support him too, so he can make his next caving expedition in the spring of 2020. For information and contact with the speleologist: see the wonderful website of Speleo Corfu.
As every bit of information can lead to new discoveries, René van Vliet calls on locals and visitors to contact him if they know a cave or cave story. Even a rumour or myth is very welcome. He can be contacted in Greek or English at firstname.lastname@example.org or on Facebook: VlietVanRene.
