What is "bowling-green"

Usage examples of "bowling-green".

There were few birds he preferred to nightjars, but it was not that they had brought him out of bed: he stood leaning on the balcony rail and presently Jack Aubrey, in a summer-house by the bowling-green, began again, playing very gently in the darkness, improvising wholly for himself, dreaming away on his violin with a mastery that Stephen had never heard equalled, though they had played together for years and years.
