|Tools for this tag|
An aqueduct is a structure for conveying water over a distance, typically using bridges to cross valleys and ravines. This tag doesn't require the aqueduct to be still working, it can also be applied to fragments.
Modern pipelines are sometimes also called aqueducts, but this tag only deals with historic aqueducts. Unlike modern aqueducts they are still referred to as aqueducts even if there are only fragments left and they can't serve their original purpose.
How to map
Draw a way along the aqueduct, or draw a closed way around its outline. Tag with historic=aqueduct.
Tags to use in combination
Other properties might be (if you know them, tag them):
- historic:civilization=* for the culture that originally constructed the aqueduct, e.g. ancient_roman
- start_date=* for the time when the aqueduct started to work
- bridge=aqueduct for parts of an aqueduct that are bridges (note that not all aqueducts are bridgelike structures, and not for all their way).
- ele=* if you know the elevation of distinct points of the aqueduct (level of the water / where once the water was) you can tag them like this
- ruins=yes if it is ruined
- wikipedia=* a link to Wikipedia's article about the feature
In some cases you might want to add
- tourism=attraction if the aqueduct is a tourist attraction.
- heritage=* if aqueduct is registered by an official heritage organisation.
Aqueducts generally tend to be long. Nowadays many of them are not entirely preserved, but you will find fragments. It is suggested to use a relation (to be defined) to join all aqueduct parts that once were continuous into one object, even if now they don't form a continuity.
