More than 100 campaigners have formed a human chain around an historic Dublin street where the Easter Rising came to an end to celebrate a court judgment declaring sections of it a national monument.
Rebel leaders who rose against British rule in 1916 fled to Moore Street when their initial headquarters at the General Post Office (GPO) caught fire in the fighting.
It was from there the eventual surrender by Patrick Pearse was negotiated.
A high profile campaign has been on-going for years opposing plans to develop parts of Moore Street into a commercial complex.
The battle has been played out in a Dublin courtroom and last month a judge declared a number of the buildings a battlefield site worthy of "unique commemoration".
The ruling widened the national monument designation applied by Irish Minister for Arts and Heritage Heather Humphreys and has cast uncertainty on the redevelopment plans.
Among those at the event on Sunday was Brona Ui Loing, whose relatives fought in the rising one hundred years ago.
Some campaigners wore period costumes and carried replica guns.
After a number of speeches, a plaque stating "Welcome to the citizens' national monument" was unveiled.
Campaigners then surrounded the buildings and linked hands.
