If any accurate information is in your pocket, please add supporting tagging as 
amenity=* (https://wiki.openstreetmap.org/wiki/Key:amenity)
name=* (if any)
and don't forget to add
source=*  (https://wiki.openstreetmap.org/wiki/Key:source)
to verify and assist future editors who may wish to understand the origins of the data they are modifying.
Happy mapping!
