The narrow canals were digged in the 17th and 18th century to provide transport for industrial area’s like Manchester and Liverpool. The canals were narrow and shallow because they had to be digged by hand. The boats transporting coal, clay and other product had to be small and long to be able to pass each other on the average 5 meters wide canals. The pre-industrial canals have been very important for the development of the English industry. When the boats were replaced by trains and lost their function, they were used for recreational purposes. This series was made on the canal between Llangollen (Wales) and between Aldermaston and Devizes.
