Giovanni Vianello was originally buried at the Kalamaria Cemetery in Thessaloniki. In 1868 the Kalamaria area became a higly appealing urban zone, so the graveyard was dismantled and most of the spoils translated to other cemeteries, The catholic tombstones, among which the Vianello family's grave, were moved to St Vincent de Paul [see topic].
