I found some interesting plans in the archives last Friday. These date from 1900 & show the existing outfall of the sewer
(& probably the drain from the culverted stream down the line of Borough Rd.), & the plan to extend them further out into the river. At the time, Tranmere pool, which was of course tidal, came quite close to Old Chester Rd. & a large area which is now Laird
's was mud. You can also see on the plans the old Tranmere ferry jetty. The area South of this was also re-claimed & became part of Laird
You can just see on the map, Green Lane & the Royal Castle hotel, which is still there (but with a different name?).
