Hello. I don't know of any geophys work at Arrowe Park but I assume the stone holes could still be located. Same for Fender Lane but the ground is wet. However at Overchurch Hill a survey north of the church was made before the Upton Bypass was built. They found no sign of the old village site but did find 4 clear magnetic anomalies. 2 of these fall exactly on the circle I proposed earlier. 2 are geometrically linked to the circle in a simple way. That convinced me the circle was real. I am trying to get Liverpool Museum to take an interest in some field work. Best wishes,
Dave Gregg
