grotto

...But, while we are waiting for the temple, can you not show us the altar?—we want to see your grotto."

Pope desired nothing better than to show his new toy, and led the way to the pretty and fanciful cave, which was but just finished.

An earlier attempt to organize a grotto in the Indiana, PA, area in the mid-1970s failed to succeed, but from it developed the informal Chestnut Ridge Explorers Association.
