HOW ROMAN COLCHESTER BEGAN One of the good things about being an during the Boudican revolt in AD 60/1 archaeologist is having the chance of over ten years after the evacuation discovering some fundamental fact of the fortress. Moreover indications that nobody was aware of before. I also emerged from the excavations have been lucky enough to experience that, at the time of the foundation the 'high' - the extraordinary of the new town, there had been feeling of elation - that accompanies considerable building operations these minor brainstorms on several including new streets and that these occasions.

Careful particularly fine object - the study of the newly prepared town plan discoveries I refer to are made of Colchester revealed hidden in the usually not in the ground but on layout of its streets the ghost of paper and always by means not of the missing fortress. This took the hands but of brain cells!

First he set out on his plan a series of strips 300 and 200 feet wide. He then marked out the northern and southern limits of the fortress and its main streets. Next he set out the main north-south minor streets by cutting these out of the 200 and 300 feet wide strips and then began to allocate plots for the individual buildings. The theoretical measurements are in some cases extremely close to the actual dimensions as taken from the Ordnance Survey plan and the theory of how the fortress plan was conceived seems to * Measurements of the fortress at Colchester.
