Ireland is an island in north-western Europe which has been divided politically since 1920. Most of the island is made up of Ireland (the Republic of Ireland). The remainder is Northern Ireland, which is part of the United Kingdom. An uncommon geological richness and the warming effect of the Atlantic produce an astonishing diversity of terrain on this lovely island, which is splashed throughout with lakes and primeval bogland. Ireland also adds further interest to the landscape through the sacred associations of so many of its physical features.

Scotland is a country that is part of the United Kingdom. Occupying the northern third of the island of Great Britain, it shares a border with England to the south and is bounded by the North Sea to the east, the Atlantic Ocean to the north and west, and the North Channel and Irish Sea to the southwest. In addition to the mainland, Scotland includes over 790 islands including the Northern Isles and the Hebrides. Edinburgh, the country's capital and second largest city, is one of Europe's largest financial centers. Edinburgh was the hub of the Scottish Enlightenment of the 18th century, which transformed Scotland into one of the commercial, intellectual and industrial powerhouses of Europe. Glasgow, Scotland's largest city, was once one of the world's leading industrial cities and now lies at the centre of the Greater Glasgow conurbation. Scottish waters consist of a large sector of the North Atlantic and the North Sea, containing the largest oil reserves in the European Union. This has given Aberdeen, the third largest city in Scotland, the title of Europe's oil capital.
