Hundreds of people have taken part in a protest in Dublin against the proposed M3 motorway route in Co Meath.
The demonstrators say the planned route, which passes close to the Hill of Tara, is an example of bad planning.
Marchers said the Government must make better efforts to preserve Ireland's cultural heritage.
Environment Minister, Dick Roche, is to make a decision soon on whether the M3 should be re-routed away from the Tara/Skryne valley.
