THE ISLAND OF SKYROS
Its position, nature and geological features.
Skyros is the largest of the four islands which make up the Northern Sporades group. It lies to the east of Euboea, its nearest land mass, and only 24 nautical miles from Kymi, by way of which it communicates with the whole of Euboea and mainland Greece. It covers an area of 208 square kilometres and has a circumference of 60 miles. Its mean longitude is 24°30' and its latitude 38°50'. Its total length measures approximately 15 miles.
The island's formation and geological features are such that quite possibly in some long-gone era there existed here two separate islands which are now joined together by a sandstone causeway some four kilometres long. It divides Skyros in two almost equal parts, each completely different from the other both in appearance and character.
