North Greendykes appears on the 1855 Ordnance Survey map as a ruin.

Well, I dont know about you, but I just love it when I see places on Old maps that were already ruins back then. Especially on very early maps. It gets my mind wondering,, just like when I see places like North Greendykes here that was already in ruins by the time of the First Ordnance Survey Map was published,
