Reconstructing Medieval Towns
The analysis of medieval towns relies on the fact that the property boundaries which define urban house-plots (burgages) are very unlikely to change over time. Excavations in York and Southampton have shown that some plot boundaries survived unchanged for a millennium or more, carefully marked out using hedges, fences or walls. Plots were laid out based on a standard perch (16.5 ft). In Burford it is still possible to find plots which have retained their original dimensions from the late 12th century.
