Hemel Hempstead: Ordnance Survey Fundamental Benchmark
Hemel Hempstead: Ordnance Survey Fundamental Benchmark
The green railings enclose the Ordnance Survey Fundamental Benchmark in Hemel Hempstead. This was built into living rock, and it still forms part of the actively maintained national network of about 200 of these marks. Its somewhat incongruous location behind a church, that is itself known as the church behind the chippy (!), can be explained thus:-

In fact the Benchmark predates all the residential development at Grovehill, and is shown in the open countryside on the 1925 large scale Ordnance Survey map on the other side of a long lost lane to a long lost house called Two Beeches.

Its published height is 144.57 metres, or 474.3 feet.

What impact the roots of the large tree next to the compound have had on the benchmark's stability is anyone's guess!
