Does this help???
The extent of the Town was still very small. There was very little south of Notte Street although the line of Southside Street ran towards the Castle, which was situated just above what is now the West Pier. There was a gate here, the Barbican Gate. From Notte Street there ran a street up to Hoe Gate. To the west there was nothing beyond Catherine Street although the wall was much further out. The West or Frankfort Gate was at the junction of routes to what was then called the Sourepool and to Stonehouse. Looe Street, Buckwell Street and the southern part of Old Town Street existed. The wall ran along the northern boundary, past Old Town Gate and then south to Martyn's or East Gate. Breton Side, where it all began on the northern shore of Sutton Pool, lay outside the wall until much later. Also outside the wall was the Carmelite Friary from which Friary Station later took its name.
