Manchester Cenotaph is a war memorial in St Peter's Square, Manchester, England. Manchester was late in commissioning a First World War memorial compared with most British towns and cities; the city council did not convene a war memorial committee until 1922. The committee quickly achieved its target of raising £10,000 but finding a suitable location for the monument proved controversial. The preferred site in Albert Square would have required the removal and relocation of other statues and monuments, and was opposed by the city's artistic bodies. The next choice was Piccadilly Gardens, an area already identified for a possible art gallery and library; but in the interests of speedier delivery, the memorial committee settled on St Peter's Square. The area within the square had been had been purchased by the City Council in 1906, having been the site of the former St Peter's Church; whose sealed burial crypts remained with burials untouched and marked above ground by a memorial stone cross. Negotiations to remove these stalled so the construction of the cenotaph proceeded with the cross and burials in situ.
