We dug up the remainder of the bricks and underneath found what is most likely an old well that had been filled in and used as a rubbish dump. The curved blocks are granite and would be quite attractive in the yard. I'm tempted to keep digging, but we are preparing to leave soon for a lengthy summer adventure and it would be unwise to leave an unattended, gaping hole. For now we will fill it in and wait for the right time.
