A Bronze Age sword has been found in the River Shannon near Banagher in Co Offaly by a local scuba diver.

Michael O’Rourke, who is a member of the Shannonside Sub Aqua Club, found the sword during a routine search and recovery exercise on the river.

Dr Andy Halpin, Assistant Keeper of Irish Antiquities at the National Musuem of Ireland, said the sword likely dates to between 1050 to 1500 BC and is an important find.

Members of the club have also recovered both Viking and Iron Age swords in the past.

A 1,000 year old Viking sword, which was found in Banagher in 2012, is on display in the National Museum as part of an exhibition to commemorate the Battle of Clontarf.
