Chester (41), the county town of Cheshire, on the Dee, 16 m. SE. of Liverpool; an ancient city founded by the Romans; surrounded by walls nearly 2 m. long, and from 7 to 8 ft. thick, forming a promenade with parapets; the streets are peculiar; along the roofs of the lower storeys of the houses there stretch piazzas called "Rows," at the original level of the place, 16 ft. wide for foot-passengers, approached by steps; it abounds in Roman remains, and is altogether a unique town.
