[1] 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.

[3][4] 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.

[6][7] 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).

[6][7][4] Gunnersbury cemetery also contains the graves of 49 Commonwealth service personnel of World War II.
