An unusual discovery has been made during restoration work in Glasnevin cemetery.

The time capsule which measures over half a metre in length was found by stone restorers carrying out work on the 1916 Sigerson Memorial in Glasnevin Cemetery. The monument was designed and paid for by the writer, poet and sculptor Dora Sigerson Shorter (1866-1918) who was active during the Irish Literary Revival, and erected in the 1920s.

Stone restorer Tony Devine was taken aback when he first set eyes on the eighty year old tube,

I thought it was a bomb.

The origins of the memorial may hold some clues as to the contents of the capsule, believes George MacCullough, Chief Executive of Dublin Cemeteries Committee,

We would estimate that there would be something of great significance in it.

Today the Director of the National Museum Dr Pat Wallace inspected the capsule with officials from the OPW (Office of Public Works), and said more in-depth investigations will take place later this week.

We will do it very carefully.

Until then the capsule remains under lock and key in a secure location at Glasnevin Cemetery.
