lead mines were well developed and concerns arose necessitating mining techniques. This raised the problem of flooding due to the digging of deep drainage tunnels, with the most important being the Milwr tunnel that leads from Loggerheads to Bagillt. Mining ended in the 1970s but quarrying is still an important local industry with two new large limestone quarries dominating the surrounding area. As a result of these quarries opening, new institutions were needed to support the community with new churches, chapels, a school and village halls being opened in the 19th century.
