Strathclyde Region takes up the western part of central Scotland. The region covers 5,350 square miles (13,850 square kilometers)--about one-sixth of Scotland's total land area. Scotland's biggest city, Glasgow, dominates the region. Glasgow lies on the River Clyde in the middle of the region. The Gaelic language is still spoken in a few parts in the northwest section of the region. Glasgow has several thousand Gaelic speakers. In recent years, an increasing number of Scots have been learning Gaelic as a second language.
