Hundreds of people have gathered at the GPO on Dublin's O'Connell Street to save what they say is an iconic 1916 site.
Campaigners claim a terrace of houses on nearby Moore Street should be preserved as an integral part of our history.
However, there are plans for redevelopment in the area, including a hotel.
Earlier this month protesters barricaded themselves into the buildings earmarked for demolition.
The case is due before the High Court next month.
