The exterior of Rathfarnham Castle is finished with a substance called lime harling, which needs to be refreshed periodically. This is a large works project which will necessitate a full scaffold being erected around the building.
There are additional works that are required to the parapets and roof which can be carried out at the same time as the lime harling. However, there is a short seasonal window in which the lime harling finish can be applied, to allow for weather conditions, which means that these works are likely to take place in Spring 2025. Funds have been allocated to undertake this project, and a senior architect has been assigned to oversee the design and completion.
In the meantime, OPW is conducting testing to verify the success of localised cleaning for the summer of 2024.
