The two maps illustrate how the town of Dalton changed between 1815 and 2015.
Overall, Dalton underwent substantial urban development over the 200-year period. The area changed from a small rural settlement surrounded by woodland and farmland into a much larger town with residential areas, an industrial zone, a hospital, a school, a hotel and an airport. The river remained in place, although a bridge was constructed over it.
In 1815, Dalton was a relatively small settlement located to the east of the river. A large forest called Dalton Forest occupied the north-western part of the area, while Hall Farm was situated south-west of the town. The River Dal ran along the southern edge of the map, with a smaller stream flowing into it. A ford provided a crossing point over this stream, and a bridleway connected the farm and Dalton. Dalton Hall was located to the south-east of the main settlement.
By 2015, the forest and Hall Farm had disappeared, and the town had expanded considerably. A large residential area had developed on both sides of the river, while several new roads formed a more organised street network. The ford was replaced by a bridge, improving access across the river. In the western part of the town, an industrial zone and a hospital were constructed. Meanwhile, a school appeared in the centre, and Dalton Hall was converted into a hotel. An airport was also built to the south of the town.
