Repair work at the Kilmainham factory on Rowerstown Lane began last week, after the building had been unoccupied since 2000.
Le Moulin, which dates from the beginning of the 19e century, was acquired by Dublin City Council in 2018.
It served as a flour mill in the early 19e century before being used for textile production at the turn of the century.
The plant ceased all operations in 2000 and has not been used since, but is listed as a protected structure by the local authority.
The enabling works, which include asbestos removal, roof repair, floor shoring, window and door repair, industrial machinery guarding and debris removal, are intended to secure and secure the building ahead of a planned conservation-focused redevelopment project.
Dublin City Council said the conservation project would eventually open the mill to the public, creating a cultural center in the Kilmainham area.
The work will be supervised by Howley Hayes Cooney Architects and is expected to take around eight months, with the final redevelopments due to take place next summer.
Work on the plant was due to start last year, but was halted in October 2021 due to a labor shortage.
A group, called the Save Kilmainham Mill Campaign, which has been advocating for the preservation and restoration of the mill since 2014, said it welcomed the development.
In an online post, the group said: “Today is the dawn of a new day.
“A day that will see the contractors start the rehabilitation works of the old mill. This should take about seven to eight months.
“I can’t wait to see how things develop over this period.”
Green Party local councilor Michael Pidgeon said the development is “really welcome news for the area as Kilmainham Mill has been in limbo for so long.
“The historic building has been left to rot over the years,” he says.
“Parts of the roof collapsed, floors collapsed and windows were shattered.”
Pidgeon says the Mill Complex “is a beautiful place and I think there’s a lot of support locally to make good use of it.
“There are plans for cultural use of the site, but these are very loose at the moment.
“I want to see more details on these plans, but I strongly believe the site needs to be usable and accessible for Dubliners to enjoy,” he says.
