Max Morgan's leg became stuck after he climbed inside the stone structure at Wightwick Manor, a National Trust property near Wolverhampton, on Tuesday.
Fire crews were called after the schoolboy's parents were unable to get him out of the small hole.
Max's head could just be seen poking out of an opening and a specialist team had to be called to help with the operation.
The youngster was finally freed after firefighters used an abrasive wheel to cut the stone in half.
He was checked over by paramedics and taken to hospital but was found to have only suffered bruising to his leg.
West Midlands Fire Service tweeted: "One of the more unusual incidents our crews and technical rescue unit have attended, but that's what we're there for #NotJustFires"
