IN June 1935, a Dublin Board of Works employee
was among a group working at part of the Dublin GPO (General Post Office), the men having been assigned to remove presses from the cellar of the GPO Customs Parcels Section, located at 10 Parnell Square.
When several presses were removed however, some mortar appeared insecure, and when touched, collapsed. Upon further investigation the employee realised he had uncovered a large cavity several feet long. Within it, in perfectly dry conditions, lay a massive arms cache. He had discovered over 90 rifles and over 2000 rounds of ammunition.
