A notable landmark at the cemetery is a monument , in the form of a black obelisk , dedicated to the Polish victims of the Katyn massacre . It was designed by Louis Fitzgibbon and Count Stefan Zamoyski . This monument was unveiled on 18 September 1976 amid considerable controversy . During the period of the Cold War , successive British governments objected to plans by the UK 's Polish community to build a major monument to commemorate the massacre . The Soviet Union did not want Katyn to be remembered , and put pressure on Britain to prevent the creation of the monument . As a result , the construction of the Katyn monument was delayed for many years . After the local community had finally secured the right to build the monument , no official government representative was present at the opening ceremony ( although some members of parliament did attend the event unofficially )
