The Charing Cross Complex - now styled as Elmbank Gardens (but sometimes popularly referred to as the Charing Cross Tower), is a multi-use commercial complex in the Charing Cross area of Glasgow, Scotland.
 Best known for its signature 14-storey tower which overlooks the M8 motorway and stands directly opposite the Mitchell Library, it was designed by Richard Seifert and constructed between 1969 and 1973.
 It is one of the tallest and most prominent high rise buildings on the western side of Glasgow city centre.
 The surface buildings of the subterranean railway station which serves Charing Cross are also an integral part of the complex.
The Queen Eleanor Memorial Cross is a replica of the medieval Eleanor cross at Charing (London), erected in the forecourt of Charing Cross railway station in 1864–5.
 It was designed by Edward Middleton Barry, also the architect of the station, and includes multiple statues of Eleanor of Castile by Thomas Earp.
 It does not occupy the original site of the Charing Cross (destroyed in 1647), which is now occupied by Hubert Le Sueur's equestrian statue of Charles I.
The Eleanor crosses were a series of twelve lavishly decorated stone monuments topped with tall crosses, of which three survive nearly intact, in a line down part of the east of England.
 King Edward I had the crosses erected between 1291 and 1294 in memory of his wife Eleanor of Castile, marking the nightly resting-places along the route taken when her body was transported to London.
 Several artists worked on the crosses, as the "Expense Rolls" of the Crown show, with some of the work being divided between the main figures, sent from London, and the framework, made locally.
 "Alexander of Abingdon" and "William of Ireland", both of whom had worked at Westminster Abbey, were apparently the leading sculptors of figures.

 It refers to the equestrian statue of King Charles I in Charing Cross, London, and may allude to his death or be a puritan satire on royalist reactions to his execution.
 It was not recorded in its modern form until the mid-nineteenth century.
 It has a Roud Folk Song Index number of 20564.
