This appears to be an aerial oblique view, enlarged from a section of larger map, which seems to have been of around 1600 (dated by artisan-mannerist strapwork cartouche). Not to scale. Shows regular, more or less gridiron lay-out of town which was established on a virgin site in the 12th century, by Bishop de la Poer. This plan shows canals not yet filled in, quintain in Market square, and Market house."
