Denbighshire County Council has announced that contractors will be on site at Corwen Pavilion from the 5th January 2015 to start the demolition process.
The aim is to complete the work by mid to late February 2015.
Works will initially involve a soft strip-out of internal areas of the property including the safe removal of asbestos.
The council took the decision to close the Pavilion in April 2010 after a structural survey confirmed there were numerous issues with the roof structure and deteriorating foundations.
The site also suffered with wet rot, dry rot, furniture beetle infestation, inadequate heating systems and asbestos.
Local councillor, Huw Jones said: “I understand that this will be a sad day for some as the Corwen Pavilion has been a key feature in the town but such a building was always going to have a limited life span and surveys carried out in 2010 showed it had finally deteriorated beyond economic repair.
"Following the conclusion of a protracted court case in which the court found in favour of the Council, we are now in a position to begin demolishing the building and I look forward to establishing a new future for the site.
"The land will be transferred back to the community but given the condition of the building, we made it very clear from the outset that we could not transfer the land with any liabilities, meaning that the site needed to be cleared and made safe in order to allow any transfer to go ahead."
Jamie Groves, Head of Communications, Marketing and Leisure, said: “The council remains fully committed to transferring the title of this land over to the community and we will be pleased to continue to support them to move forward and find the necessary funding for a sustainable building.”
