Use for referencing a plaque's entry on Open Plaques, the international Open Data register of commemorative plaques.


Use the so called machine tag on the plaque's website at as an OSM-Tag exactly as it is shown on the website.

Generally best used with historic=memorial with a required memorial=plaque, and an optional appropriate inscription=* and/ or name=*.

Note that Open Plaques collects markers that state or imply that the subject was physically at the marked location at a particular time in the past. For example, this excludes a memorial inside a church (except where they make a point that 'Xyz worshipped here'), a road named after someone famous who did not actually live there, and items (statues, clocks, plaques, etc.) commemorating a monarch's anniversary (where the monarch is not visiting the town to unveil it). There is also an exclusion on building 'foundation stones'.

The geolocation on OSM is likely to be more accurate than that on Open Plaques.
