Demonstrators take part in a sit-down protest on O’Connell Bridge (Brian Lawless/PA)
The protesters sat on the north and south sides of the bridge, blocking traffic from crossing Dublin city centre.
The 'Take Back the City' protesters had initially gathered at the Garden of Remembrance at 1pm to demonstrate before marching down O'Connell St under a garda escort.
Speaking at the gathering, the spokesperson for 'Take Back the City' asked people to stand up against Fine Gael and Fianna Fail, adding that the government is "gentrifying the city and forcing people out of their communities."
"Stand up against Fine Gael and Fianna Fail privatisation policies. They’re gentrifying the city and forcing people out of their communities. It’s about time that people stand up and prove that housing is a human right for everybody," they said.
'Take Back The City', who have hit headlines for occupying vacant properties in Dublin's north inner city, said it's "time for the movement to grow".
Campaigners have been calling for vacant properties to be subject to Compulsory Purchase Orders to end evictions.
As part of their "nationwide action", rallies and protests were also organised in Cork, Waterford, Sligo, Wexford, Kildare, Limerick, Sligo, Derry, Belfast, Drogheda, Maynooth and Bray yesterday.
