Chillon Castle belongs to the Canton of Vaud and is entrusted to the Chillon Castle Foundation for its use and conservation.
Any team tasked with conservation work on an historic monument must fully respect and promote its continuity.
The contractor, i.e. Chillon Castle Foundation, oversees the funds allocated to preserving the castle; the Technical Commission has been responsible for overseeing construction works since 1889; and the project manager, i.e. the castle architect, coordinates the work carried out by specialists and external companies.
Official experts ensure that the code of ethics is adhered to, while user representatives ensure that the building is properly managed and that operations run smoothly.
After the scientific restoration of the castle by archaeologist Albert Naef, the two world wars led to severe cuts to funding for conservation work at Chillon Castle. Work has been ongoing since the 1970s to remedy this delay.
The planning phase of conservation and maintenance work consists in identifying causes of deterioration and establishing inventories as well as a five-year plan.
There are various causes of deterioration to the castle: natural damage, wear due to visitors, outdated technology, or changes to how the castle is run. Each element of deterioration is inventoried, logged in a database and mapped on the castle site plans.
The process is then oriented in line with the level of deterioration and hence urgency, i.e. whether a one-off urgent procedure is required, or a longer term, more localised construction project. This method helps financial estimates to be made for various construction projects and maintenance campaigns.
Long-term planning is then laid out for the next five years. This helps optimise project timeframes while also taking into account level of urgency and the Foundation’s budget.
