Geography and natural history

The mainland of Scotland comprises the northern third of the land mass of the island of Great Britain, which lies off the northwest coast of Continental Europe. The total area is 30,977 square miles (80,231 km) with a land area of 30,078 square miles (77,901 km), comparable to the size of the Czech Republic. Scotland's only land border is with England, and runs for 96 miles (154 km) between the basin of the River Tweed on the east coast and the Solway Firth in the west. The Atlantic Ocean borders the west coast and the North Sea is to the east. The island of Ireland lies only 13 miles (21 km) from the south-western peninsula of Kintyre; Norway is 190 miles (305 km) to the northeast and the Faroe Islands, 168 miles (270 km) to the north.

The territorial extent of Scotland is generally that established by the 1237 Treaty of York between Scotland and the Kingdom of England and the 1266 Treaty of Perth between Scotland and Norway. Important exceptions include the Isle of Man, which having been lost to England in the 14th century is now a crown dependency outside of the United Kingdom; the island groups Orkney and Shetland, which were acquired from Norway in 1472; and Berwick-upon-Tweed, lost to England in 1482

The geographical centre of Scotland lies a few miles from the village of Newtonmore in Badenoch. Rising to 4,413 feet (1,345 m) above sea level, Scotland's highest point is the summit of Ben Nevis, in Lochaber, while Scotland's longest river, the River Tay, flows for a distance of 117 miles (188 km).
