In order to carry out these works the Castle building was closed to the public from November 2016 to April 2018. We had hoped to have the castle open to visitors during project works throughout, but as we started undertaking the trails it became clear that the amount of interruption and intervention by contractors would not be compatible with visitors in such a small confined space. We considered a number of partial opening models but each we felt would only prolong the work beyond what is reasonable. We therefore took the decision that closing the Castle was the quickest and most effective way to get the work done.
In terms of the main project itself, the works saw the Castle emptied of its collection – the first time this has happened in over 100 years – and then handed over to the main contractor. They then set about installing protection inside the building; mainly in the form of plywood or hardboard. This gave the Castle a strange 'yellow' appearance inside, and with the installation of festoon lighting throughout, the building more resembled an old mine than an Edwardian holiday home! Scaffolding was erected at the Castle in order to reach all areas where work was to be carried out. This required the most spectacular scaffold Holy Island had ever seen and could be marvelled at for miles around. The process of removing cementitious material from the walls began internally during winter 2016 and work commenced outdoors in Spring 2017.
Eventually over 300 square metres of the external walls would be covered with a 'sneck harl' as an extra layer of protection against the elements. Most of the internal walls would be newly covered with a fine lime plaster to help with evaporation of the moisture trapped in the structure. On the roof the drainage system would be modified to take water away from the building without effecting any of the walls, while all 108 windows would be refurbished and reinstalled. A few extra jobs popped up we weren't expecting, such as the careful replacement of all three tracery windows on the north elevation, and the painstaking uncovering of 17th century wall paintings in the Kitchen.
