When ripping up the earth for the Vestigial Lawn, I kept finding scraps of some sort of tile. Here are three of the largest pieces:
These differ from brick, obviously, and my best guess is that someone disposed of a pile of … somethings. I originally thought these might have come from an old patio but if they did the patio was either very small or someone had hauled almost all of the tiles away when it was abandoned: these scraps were everywhere but there were only enough of them for five wheelbarrow loads. Since there is no practical use for a tiny patio and I’m darned positive no one has bothered to haul off any waste materials on this property, ever, these fragments must have been junked.
The underside (A) has a lip and the top (B) has a series of ridges (I’m just guessing here. The top and bottom could also be reversed). The edges are rounded but what’s left of them looks square. What are these? My best guess is interlocking roof tiles but these seem really impractical for a roof.
