The Department of the Environment yesterday served an Urgent Works Notice on the agent for the owner of the former National School in Bushmills.
The school is a listed building built as part of a nationwide initiative launched in 1830 by Edwin Stanley, Chief Secretary for Ireland and later British Prime Minister.
The building is not watertight and is not well secured, according to the DoE. The department claims it has tried repeatedly to encourage the owner to take steps to remedy the situation.
It has now issued a notice which outlines the action it will take to carry out emergency works if the owner does not initiate these within seven days.
