This is a collection of years on facades.

https://year-on-facade.uk/

In order to be added to collection the location needs to meet the following requirements:

1. The year must be on facade and be part of the building and should be associated with it (examples):
   • Year of the construction / reconstruction, i.e. erected, enlarged, rebuilt ✅
   • Commemorative plaque ❌
   • Year when the organization located in the building was established ❌
2. Year must be written with arabic numerals.
3. The building must be located in administrative boundaries of particular city.
4. Be verifiable via Google Street View.
   • Note: only Street View and not "Photo Sphere"

It is OK to replace existing points in case the replacement:

1. is in the heritage registers e.g. in Historic England or Fredede og Bevaringsværdige Bygninger
2. is on the building with a unique design or history
3. or makes distribution of the points on the map nicer (i.e. less crowdy)
