A cave=grotto is a human-made or human altered cave, that are built with the specific purpose to offer an interesting landscaping element in a park and/or to offer a leisurely attraction (sometimes romantic).
Grottos are a specimen of historic=folly's. However, I propose to group them under natural=cave as that is the most natural (sic!) place to put them after their resemblance to real caves.
Holes in mountains that are man-made for other reasons (storage, extraction of minerals, shelter) should be tagged as man_made=adit or their respective combination of building=* and underground=yes
A specific type of grotto is the Lourdes grotto. I proposed a tag for that as well.
Rationale
Grotto's are man-made holes in mountainfaces (sometimes the mountain face is man-made as well), or existing caves (or quarries or adits) that are enhanced. Grottos sometimes are made to resemble a natural cave as closely as possible, but sometimes very ornamental.
Grottos should be large enough for humans to enter. See Grotto on Wikipedia
Tagging
Tag a node, way or area as natural=cave cave=grotto.
For smaller grottos inside an existing mountainface, a node can be used. Larger grottos can be tagged as way to tag on the mountainface, or as area when the entire outline of the grotto is tagged. In the case of an area, the underground=yes should be used. If the grotto is situated inside a purpose-built mountain, node (smaller grottos) or area (larger grottos) should be used.
- name=* - to use a name
- description=* - a description, if applicable
- year=* - the year the grotto is erected.
- amenity=place_of_worship - if the grotto is a lourdes grotto.
- refitted=yes - if the grotto is a natural cave that has been altered.
- anthropogenic=yes - if the grotto is entirely human-made
