My view is that if it is something that is still there on the ground (e.g. the
ruins of an old tin mine), then it should go in the main database.   If there is
nothing physically to see, it belongs in a specialist historic map. I haven't
thought about how to make this separate map though....

That is the 100 dollar question ;)
What is difficult to separate is where an object IS still on the ground but now has a different designation. For example where a railway line was ripped up but is now in the process of being restored. Where there is historic information for an existing object, some information would need to be stored in each database?
