Buildings as evidence
Buildings are a valuable form of evidence for urban history and can often provide crucial evidence for dating a town or city's development. You can sometimes see the survivors of the medieval or Tudor past - sometimes half-timbered, with their small windows and low ceilings.
'The insides of buildings are also worth considering ...'
On the other side of the coin are the working class terraces of the 18th or 19th centuries, with their narrow fronts and two-up, two-down layout.
The insides of buildings are also worth considering, since they often tell us about the changes in a building's use: the Georgian town house now turned into flats, or offices, or the Victorian villa turned into a school. In their own way, these changes are part of the ever-changing, evolving urban landscape that we see all around us.
