Hello.
I live in Wainscott. I was recently gardening when I uncovered a manhole with grass growing over it. I investigated and there is a square shaft that goes approximately 2 feet down. It then opens into a bell-shaped chamber with perfectly smooth concrete walls. It is approximately 5 feet in diameter. The floor is just mud and over the years some rubbish has been put down there. I dug down approximately 2 foot but it's just more mud with various layers of rubbish, ie tiles and broken bricks.
Does anyone have any idea what this could be? There are nu rungs or ladders and no other holes are markings in the concrete walls. I am tempted to just keep digging but I could do this for a long time! Our house was built in the fifties and we have lived there for around 6 years.
What could this be???
