Maybe not quite as mysterious as the great pyramid's

but it's gotta be close

those dry stone walls in England , some are over 3,000 years old , Yorkshire alone has over 5,000 miles of them ,

stone walls going off in all directions , randomly , or , at least what looks randomly , I'm guessing there was a great deal of alcohol involved

just dry stones , stacked on top of each other , no mortar , but here we are thousands of years later , and they still stand

who built them , how many people did it take , where and how did they transport that many stones

there's like 25,000 miles of these walls throughout England , and it's believed it would take 40 million “man days” of labor , I have no clue how to convert that down into years and people it took

did they just live out of tents and just moved along as they built the wall, how many horses and carts would it take to keep the workers busy

these walls completely amaze , and baffle me
