The coal industry also left its mark on the town. From the late 17th century onwards coal was dug in increasing quantities in the region. Mining was centred around the rivers, for transportation by sea to other parts of the country, and Chester-le-Street was at the centre of the coal being dug and shipped away down the Wear, so a centre of coal related communication and commerce. At the same time the growth of the mines and the influx of miners supported local businesses, not just the many inns but new shops and services, themselves bringing in more people to work in them. These people would later work in new industries established in the town to take advantage of its good communications and access to raw materials.
