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 [[tide|tidal]] inlet of [[Wallasey Pool]]. The construction of a [[cofferdam]] enabled [[land reclamation]] and excavations to take place. After the establishment of the Great Low Water Basin, [[Morpeth Dock]] and [[Egerton Dock]],<ref>{{citation|url=http://www.merseysideviews.com/Merseyside%20Docks/Birkenhead/1850-map.htm |title=Birkenhead Docks map (1850) |publisher=Merseyside Views |access-date=13 October 2007 |url-status=usurped |archive-url=https://web.archive.org/web/20061023150644/http://www.merseysideviews.com/Merseyside%20Docks/Birkenhead/1850-map.htm |archive-date=23 October 2006 }}</ref> the Great Float was formed between 1851 and 1860 from most of what remained of Wallasey Pool.<ref name="Trading Places: Birkenhead Docks History" /> The plans for its construction were originally shown in 1844 in the ''Liverpool Standard'' newspaper.<ref>{{harvnb|Bidston|1978|pp=12–13}}</ref> Designed by [[James Meadows Rendel (engineer)|James Meadows Rendel]], protégé of [[Thomas Telford]], the scheme was managed by the Birkenhead Dock Company until a financial crisis in 1847.

[[Dry dock#Graving|Graving dock]]s were built in 1864 and 1877, on the south side of West Float.<ref name=Ashmore156>{{harvnb|Ashmore|1982|p=156}}</ref> Established in 1853, [[Thomas Brassey]]'s [[Canada Works]] was built to the east of the Great Float.<ref name=Ashmore156 /> The entrance to the Great Float 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 mill]]ing centre, with numerous companies, including [[Rank Hovis McDougall|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.

[[LCT 7074]] ''Landfall'' is the last remaining [[tank landing craft]] which had served during [[Normandy landings|D-Day]]. The landing craft was one of the Warship Preservation Trust exhibits and had sunk in East Float following the liquidation of the trust in 2006. The craft was refloated on 16 October 2014.<ref>{{cite web|url=http://www.liverpoolecho.co.uk/news/d-day-landing-craft-raised-wirral-7938679|title=D-Day landing craft to be raised from Wirral dock|publisher=[[Trinity Mirror]] Merseyside|access-date=16 October 2014}}</ref><ref>{{cite web|url=https://www.theguardian.com/uk-news/2014/oct/15/d-day-tank-carrier-landfall-refloated-liverpool|title=D-day tank carrier Landfall refloated for restoration|publisher=Guardian News and Media Limited|access-date=16 October 2014}}</ref>
