What's that coming out of the ground, is it a chimney?
Excavation to the west of the boundary wall has indeed revealed the truncated remains of a giant chimney. This is shown on the 1860s engraving as protruding into the pond, so its discovery suggests that our ideas about the location of the pond were out by about 5 metres. Unfortunately this means that the water wheel also shown on the engraving is likely to be lost beneath the 1960s office building to the north.
