The Valor Ecclesiasticus of 1535 is the most important document for analysing the economic conditions of the monasteries in England on the eve of their dissolution.
The information contained in this material, however, does not tell us the whole story. Especially, coal-mining, which was an important activity of the monasteries in northern England during this period, is almost entirely neglected in this document.
Therefore, the author has investigated the economic conditions of Durham Cathedral Priory at the time of its dissolution through its own documents, and has thrown some light on the coal-mining operations in this priory.
The details of its management have been elucidated from the 14th century through the first half of the 16th century.
