They Called Her Babylon is an album by British folk rock band Steeleye Span.

The title track deals with the Siege of Lathom House in 1644, during the English Civil War, during which Charlotte Stanley, Countess of Derby, held out for four months against Parliamentarian efforts to take the house.

New to the band with this album was guitarist Ken Nicol, while drummer Liam Genockey, who had played on Time, returned.

Highlights of the album include 'Van Diemen's Land', a song about poaching and deportation to what would eventually be called Tasmania; 'Heir of Linne', a classic ballad of riches lost and regained, and 'Child Owlet', another traditional ballad whose gruesomeness is underlined by Prior's powerful vocals.

Others saw the album as representing a continuing decline of the band, attributing it to the aging of the band's core members, and noting that Prior's voice, while still strong and effective on songs like 'Van Dieman's Land' and 'Child Owlet', does not seem to have its top range any more.
