in Kollmar, SH·counted·4 all time
A lighthouse built by people, typically a tower with a beacon, lantern room, and coastal or waterside setting.
Counted, not streamed: Man Made Lighthouse has no time series, so it is read as a footprint across places. All-time count by city.
Things that physically exist: street furniture, signs, buildings. All-time counts.
