They may look like out of place lampposts but Holme Posts are part of history. The posts were buried in 1848 to measure how much the land sunk after Whittlesey Mere, once on this site, was drained. The peat lake floor had been soaked in water but after drainage, the peat shrank, as did the height of the land. The top of the posts, once level with the ground, are now around 4m above it. The posts are generally accepted to mark the lowest land point in Great Britain at 2.75m below sea level.

Burnhams Mere was created when the area was cut for peat, resulting in this wildlife haven.

Great road through the great fen! Water on all sides, you get a good view for miles around. Check which way the wind is blowing before you set off though!

Congratulations, you are at the lowest point in the UK, 3m below sea level. The top of the iron posts marks ground level when the fen was first drained in 1850. Since then they have been progressively exposed by the shrinking peat until the tops now stand 4m above modern ground level.

Not far off this lane is Holme Lode to the nature reserve where you can see the Holme Fen posts which have monitored the shrinking of the Fens as a result of their drainage; a sobering sight to see.
