 Practically every village around the city had a coal mine and, although these have since disappeared as part of the regional decline in heavy industry, the traditions, heritage and community spirit are still evident.The 19th century also saw the founding of Durham University thanks to the benevolence of Bishop William Van Mildert and the Chapter in 1832.Durham Castle became the first college (University College, Durham) and the bishop moved to Auckland Castle as his only residence in the county.
