Dyserth is mentioned in the Domesday book of 1086 as follows, it being at the time listed under Cheshire: Dyserth also had a nearby castle, which suffered at the hands of Llywelyn ap Gruffudd; destroyed after a six-week siege in 1263. The remains of the castle were quarried away during World War I. The oldest industry in the village and surrounding area is mining, with lead, copper and limestone just some of the minerals being mined locally in the past. These quarries are still visible and form a major part of the village's geography, though mining ceased when Dyserth Quarry closed in 1981. Traditionally, there has been a strong Welsh language speaking community in the village and until recent times many families and village folk knew, or knew of, each other. This is typical of a rural community whose life often centred on its many churches and chapels. Many of the village's families have their roots in agriculture, with many notable farms in or around Dyserth, including Hottia, Bryn Cnewyllyn and Ty Newydd. A recent drive to reawaken a feeling of village pride has had some success, through promotion by Dyserth people and village-based events and organisations. Local work has gone into sprucing up parts of the village, notably the High Street, parks and entrances. The village has several community and environmental organisations, some with a long history. For example, the Dyserth & District Field Club was founded in 1911. The village recently received an apposite grant from the National Lottery Heritage Lottery Fund to refurbish the community hall.
The Dyserth branch line was opened by the London and North Western Railway in 1869 to tap limestone quarries and a lead mine. A passenger, parcels and goods service was introduced in 1905 to serve local needs and an expanding holiday industry. The company designed and built a single carriage, steam-powered Motor Train for such lines, with the Dyserth Branch using the first example. The passenger service was a success before the First World War. Services were doubled and an additional unit provided for the motor trains. After the war the motor trains were replaced by locomotive-propelled push-pull trains. Road competition and the 1926 General Strike ate into profits, leading the London, Midland and Scottish Railway to withdraw the passenger service in 1930. The line remained open for minerals, parcels and general goods until the end of November 1951, when parcels and general goods traffic ended, leaving just coal to and limestone products from a quarry in that village. Coal traffic ended in May 1964, with lime and limestone traffic continuing until the line officially closed completely on 7 September 1973, although at least two special trains took stone away in 1974. The tracks were lifted in 1980, with the former trackbed now converted into a mixed-use footpath and bridleway.
