It's sort of grid iron pattern streets on the south side of the High Street; on the north side that's all disrupted by the castle and, as far as one can tell, when the town and the area around it, the Rape of Lewes, was ceded to William De Warren, most of the local powers of the Town Council such as it was were taken away and subverted and the town became a minorial borough and although it sent Members of Parliament to Westminster from the end of the thirteenth century, it only had a very sort of ramshackle corporation, because the lords of the manor of Lewes kept control fairly tightly on what the town was actually allowed to do and on its internal freedoms.
