The most visible impact of the proposed project will come from the trimming of the ivy currently covering the castle walls. The ivy will be cut back heavily ... removing weight from the structure and hopefully focusing the survivng ivy on new growth and reducing root expansion. The ivy roots penetrate the masonry and if the ivy is killed, the roots die ... leaving voids. Water can enter these voids and freeze damage can be worse than from the slow growth of the ivy. The long-term best solution is probably to kill the ivy and repoint/consolidate the masonry. That is a much bigger project than our current scope and a full archaeological study needs to be completed before such work would be approved.
That comprehensive archaeological study could conceivably be an extension to Project 3 ... depending on available funding ... but it likely a separate project in itself.
Trimming the ivory and coppicing selected trees will give us our castle back, however. Hopefully, next summer's visitors won't have to imagine that the "tree with a window in it" is our castle.
