Home Sweet Home campaigners have linked arms around Apollo House in a bid to keep those living there sheltered.
The organisation is supported by many Irish artists including Glen Hansard, Kodaline, Hozier and others to help tackle the homeless crisis in Ireland.
The High Court had delivered notices to those squatting in the abandoned building to leave today - but the campaigners argue that if they leave they will have no where else to go.

Home Sweet Home have asked the court to extend their notice so that those living in Apollo House have time to find somewhere else to live.
In a live video captured by TodayFM, the video shows hundreds of people joined together in a peaceful protest.
