My home built stone crescent in Brunswick, Maine

This is a small stone crescent I built myself on my own property in Brunswick Maine, U.S.A. It measures 33 feet across and the stones all are less than 3 feet tall. The center stone has a 2 inch through hole towards the top. I’ve been enlarging this over the years and it’s built by hand with no mechanical equipment. I plan on enlarging it as I acquire more larger stones.
