People are being encouraged to hang spare coats on the Ha'penny Bridge for the homeless.
Printed signs on the walkway tell people to "leave one if you have one, take one if you need one".
The 'Warm For Winter' initiative is hoping to supply rough sleepers with coats for the cold weather.
Patrick Fryers, who started the 'Warm For Winter' initiative, hopes it'll spread to other locations.
"Even if it's only one coat, bring it to anywhere you think someone might need it and hang it up", he said.
Patrick will continue to collect coats and hang them on the Ha'penny Bridge.
He is encouraging people in other areas to do the same.
"Imagine everyone else doing the same thing, it's not a big task", he said.
Patrick has decided not to cover the coats in plastic, over fears it could blow into the Liffey.
