"interesting to map dismantled city gates as historic=city_gate"
It is OK to map ruins/remmants, archeological site - but note that
completely destroyed objects should NOT be mapped.
typically city gates have had such a huge impact on the structure of
cities that they normally persist even if there is nothing left in
physical terms. The roads that once passed the gates are still the
"arterial" roads, the squares are still named after the gates
(typically) and the whole area often still has that name (e.g.
referring here to my birth town Tübingen, where everybody would still
know "Neckartor" (dismantled 1804), "Lustnauer Tor" or "Haagtor" (and
2 others, all of which non-existent physically but very existent in
daily life/communication, e.g. to set up a place to meet)).
Actually we recommend to map such objects with the razed: prefix for
objects that once existed but now there are only barely remnants or even
indirect indications thereof.
As long as there is a historical interest in them and there is a slight
indication of its position we are willing to map them in the historic map.
Cheers,
Zecke
