About London Benchmarks
A group dedicated to Benchmarks, Trig Points and other Ordnance Survey ephemera in London. We will also accept Prime Meridien markers, but please not from the Greenwich Observatory itself, that reflect the purposes of Ordnance Survey markings [ie to assist in mapping and surveying].
All shots should be taken in London within the M25 and the benchmark or trig point should be a significant focus of your shot, not just a peripheral fragment.
The Group Admins reserve the right to tidy up occasionally.
There is some background information about benchmarks here, or see www.bench-marks.org.uk/ and www.trigpointinguk.com/.
