At this point the Dee Branch makes a right-angled bend, which may well mark the original junction of the Wirral Line of the Ellesmere Canal with the Chester Canal. Thei came from a basin on the Dee into the righ-hand side of this picture, and seems to have continued past the tower and along by the city wall to Northgate locks, then a staircase of five. Later the Wirral Line joined it somewhere (I believe at the spot shown here), Later still the Wirral LIne was modified to join the Chester tewo locks higher up.
