I concur. Nothing here anymore. Staying in a B&B just over a mile away, handy :)

Yup - the Waterworks have been built slap bang ontop of whatever trig was here.. I used Agent Mancusos HY4657409656 data to nail the position

It showed up on my GPS (included in the Agentmancuso POI file) as a Rivet at HY 46574 09656 but I failed to get very close to the location. The non-pillar FB 12112 nearby has also gone :-( OS trig archive has Tower Hill Water Tank, Rivet, computed 1961, maintained 1986. Not listed as destroyed, FWIW.

There is a triangulation pillar marked at this location on my Explorer 461 from 2003. (It is just next to the water tank.) I am checking with the OS to determine whether this is a misprint, but am sure that there is no TP here: if there was, it would have been destroyed by the work that seems to have recently been undertaken...
