Great Float - History

History

Unlike in Liverpool, where the docks were built along the coastline of the River Mersey, Birkenhead Docks were designed as an inland system by enclosing the tidal inlet of Wallasey Pool. The construction of a coffer dam enabled land reclamation and excavations to take place. After the establishment of the Great Low Water Basin, Morpeth Dock and Egerton Dock, the Great Float was formed between 1851 and 1860 from most of what remained of Wallasey Pool. The plans for its construction were originally shown in 1844 in the Liverpool Standard newspaper. Designed by James Meadows Rendel, protégé of Thomas Telford, the scheme was managed by the Birkenhead Dock Company until a financial crisis in 1847. By 1858, the rights to dock ownership and revenues were transferred to the Mersey Docks and Harbour Board, based in Liverpool.

The entrance was originally through the Great Low Water Basin, which was enclosed in 1877 as Wallasey Dock. After this date, access from the river was provided via Alfred Dock and Morpeth Dock.

The Resurgam, one of the first submarines, was tested in the Great Float in 1879.

In the early 20th century, Birkenhead Docks became an important flour milling centre, with numerous companies, including Joseph Rank Ltd and Spillers, located on the Great Float's quaysides. In the 1990s, long after the industry had gone into decline, most of these buildings were demolished. Two large warehouses remain, which have now been converted into residential apartments.

The Great Float was the site of the Warship Preservation Trust's exhibits from 2002 until its closure in February 2006.
