Thousands visit the National Museum of Ireland to see the Derrynaflan treasures.

An estimated 5,000 people visit the National Museum of Ireland (NMI) in Kildare Street, Dublin on the day the Derrynaflan treasure trove is revealed to the public for the first time.

One hour after the priceless items went on show, some 600 people had passed through the museum doors. NMI staff had their busiest day since the Easter Rising 25th anniversary exhibition went on show in 1941.

The Derrynaflan treasures consist of a chalice, paten, liturgical strainer and a basin. It is thought that the hoard was buried in the ninth or tenth centuries by Viking raiders.

The exhibition is on show for a month before the artefacts go to Britain for conservation work. This process is expected to take about a year.

The hoard, considered to be the greatest archaeological discovery of the century, was found on an area known as the Island, grassland rising from the Lurgo Bog near Thurles in County Tipperary. The land that makes up the Island are jointly owned by dairy farmer John O'Leary and his neighbour Denis O’Brien.

While pleased about the find, John O’Leary is annoyed about how the discovery took place,

Somebody using a metal detector and using a spade and shovel on my property without permission.
