It consists of shaft with a light on the top, and originally had the dual purpose of being a monument and of illuminating the entrance to the tunnel.
It was designed by Herbert James Rowse, and was one of a pair, but the monument that was on the Liverpool side of the River Mersey no longer exists.
[1] Two identical structures were designed by Herbert James Rowse to be placed near the entrances to the tunnel, one on each side of the River Mersey.
The monuments were built by McAlpine and Sons, and the decorative metal work was carried out by H. J. Lloyd of H. H. Martyn & Co..
The construction of the monuments was complete by the date of the official opening of the tunnel by King George V on 18 July 1934.
