I recently had occasion to visit the Addolorata cemetery in order to locate and photograph some graves for a military historical presentation which I am working on.
The duty clerk could not have been more helpful, giving me the exact location of the graves and also, patiently, giving me detailed instructions on how to locate them. Unfortunately, I soon got lost. A very helpful attendant took pity on me and quickly took me to the graves .
Given the size and complexity of the cemetery, surely it would make sense for detailed plans to be made available on site for sale to the public or at least for such a plan to be put online for people to download.
