The project, which has received Heritage Lottery Funding, will replace internal iron elements that are starting to corrode and split the stone and re-point the whole structure with suitable mortar. This will stop water entering and causing further damage. There is more information in the 'Science' section.
We are also carrying out historical research into Sir William Brass as well as geological and building research into the use of the stone. This will be presented in a project book, released later in 2016.
