The cave of Ellinokamara οn the Island of Kasos has been νisited in the course of time by travellers and archaeologists who have provided us with detailed descriptions and sketches both of the interior and of the exterior of the cave. The first sketch we have was made by L. Ross in 1843 while passing through Kasos during his travels in the Aegean archipelago. The entrance wall has been dated to the second half of the 5th century BC, regardless of the marks made by masons that he had recorded. Although we recognize the difficulty in dating the construction we cannot, of course, base ουr assumptions solely οn the manner the wall was built, since similar constructions existed during the Minoan l Mycenaean period and even later.
References:The historical centre of Briançon is a strongly fortified town, built by Vauban to defend the region from Austrians in the 17th century. Its streets are very steep and narrow, though picturesque. Briançon lies at the foot of the descent from the Col de Montgenèvre, giving access to Turin, so a great number of other fortifications have been constructed on the surrounding heights, especially towards the east.
The Savoyards made two raids into French territory in 1691 and 1692. As a result, Vauban was dispatched to inspect the frontier defences, which had been ill-equiped to deal with the attack from Savoy. He returned to the area in 1700 to check on the progress that had been made since his first visit. When Vauban visited Briançon, work on the defences had already started under a local engineer, Monsieur d"Angrogne in 1692.
