That's pretty much the case in York - for example if you zoom out from 
http://www.openstreetmap.org/way/145367452 (a corner of the old Roman 
wall) you can see that only the still-existing part of that wall is 
mapped (this is separate to the new medieaval wall which is mostly still 
complete and mapped separately to the west).

That's certainly where I've added stuff in the past - unfortunately a 
server crash meant that everything that I added to OHM was lost. The 
server's back now, so second time lucky I guess...

Depending on what the original mapper was trying to do, OHM might not be 
the best option - if they're trying to create a map highlighting 
historic sites then some sort of GIS package (or even JOSM) might be a 
better idea.

Best Regards,
