Hi Manuel Lino Do Vale,
Thank you for your contribution! 

I've reviewed OSM and noticed that the following element already exists: 
"Parque de Lazer de Nossa Senhora da Torre" (leisure=playground)
https://osm.org/node/11816790070

Could you please confirm if this matches the details in your note? If so, either you or I can mark this note as resolved.
