Could you do a screen shot and point to the area you mean?

What does the place look like from the ground?

At this point, I see some "x" shapes but similar things can be seen in fields around there, so I'd tend to suspect it's created by a combo of the image technology and the farmer's planting or harvesting.

Old temples and so forth may be in the area (it's really possible) or old forts. Stone temples are pretty easy to find... but you have to know where to look to find wooden temples.

Easiest way to answer what's there is not by an aerial satellite photo. It's by going there, asking your granddad what he found on the land, and talking to the local museum and historical societies. They'd really know what was going on.

They look like holes in the earth with trees surrounding them. Maybe they are just water holes.

Am I right in thinking that there are two next to each other in one area and then there's one by itself in another area?

on the ground there are lumps and bumps, alot of pottery has been found along with glass bottels.

i try and get a picture from the ground.

but the field alone is massive, if it is a structure its the same size of at least 6 football pitches.

i shall have a look at the local archives

I think youll find its simply an old cros-ploughing pattern Look closely and youll see the lines
