Newcastle-upon-Tyne (186), a city and county of itself, and chief town of Northumberland; situated on the N. bank, and 10 m. from the mouth, of the Tyne, 275 m. N. of London. The old town extends some two miles along the river bank, and with its crowded quays, narrow winding streets, and dingy warehouses, presents a striking contrast to the handsome modern portion, which stretches back on gently rising ground. The cathedral is an imposing and interesting architectural structure, while the public buildings are more than usually ornate. The Colleges of Medicine and of Science are affiliated to Durham University. There are several fine libraries, theatres, hospitals, and charitable institutions, and the city is especially well off in the matter of public parks and pleasure grounds. Three bridges (including Robert Stephenson's famous High Level Bridge) span the river and connect Newcastle with Gateshead. It is the chief centre of the English coal trade, and is a busy hive of all kinds of metallic, chemical, machinery, and kindred works, which give rise to an immense and ever-increasing shipping trade. As a centre of shipbuilding the Tyne is second only to the Clyde.
