Glasgow - the port:

The River Clyde has always been crucial to the city of Glasgow. It is the reason for the city's position. It stretches around 100 miles from a small stream in Lanarkshire to a wide firth at Greenock. In the 19th century the Clyde was buzzing with ships about to travel all over the world. Before the days when air travel became common, the Clyde was a major port for people and goods travelling all over the world. Duncan McCrone, who grew up by the river, describes how busy the Clyde was with traffic before the docks fell into decline.
