It is wonderful that this work was finally done. From what I have read, the Edicule was in danger of collapse over 70 years ago when the British authorities installed the scaffolding around it, but no permanent restoration was performed until now.
While the Edicule is now secure, I have also read, unfortunately, that the foundation of the church itself also needs repairs, and could be in danger of collapse if nothing is done.
