Post from our roving correspondent 'Mr Steve'.
Last year I went to Fort Nelson which is located in the hills just north of
As I only took photos of those things that interested me I cannot give you a full guided tour so I will just pick out some of the more interesting items and occasionally drip them in from time to time. This short article therefore is about the giant mortar which stands outside the fort.
It was 1854 and the British government wanted a big mortar however it also needed to be easily transported (i.e. an IKEA version) so they put out a requirement for tender and given that they were in the middle of the Crimean war they wanted it urgently.
One of the people who submitted plans was Robert Mallet, the son of an Irish iron foundry owner; he had graduated in Science and Mathematics and was also extremely interested in earthquakes and their energy waves. His proposal was that if you threw up a big enough bomb then it didn’t have to actually hit its target to do really serious damage. Using his iron manufacturer skills he submitted a plan for a giant mortar made up from multiple parts and which would sit on three layers of heavy bulk timber rather than on a purpose built base.

Prime Minister, 1855-58 and 1859-65
Unlike other follies these were actually fired, a grand total of nineteen rounds with each shot causing various amounts of damage to the first mortar and with no prospect of curing the faults the project was cancelled.
Claimed by many websites as the largest mortar ever made, each shot weighed over a ton and had a range of around a mile and a half.
(However according to Wikipedia:The largest mortars ever developed were the Belgian "Monster Mortar" 36 French inches; 975 mm; 1832, Mallet's Mortar 36 inches; 910 mm; 1857 and the "Little David" 36 inches; 914.4 mm; developed in the United States for use in WW2.All three mortars had a calibre of 36 "inches", but only the "Monster Mortar" saw action ) and it also depends on how you classify the seven WW2 German Karl Mortars.
The unfired gun is the one in the picture whilst the test gun is also still in existence and is currently at the army base at Woolwich.
Mallet went back to his study of earthquakes; something for which he was clearly much more suited to because he would later became very highly respected for his work on seismology.
There are much better photos easily available on line and which show the shear scale of this thing much better than my long distance picture does, I do think that you might need a mate to help you with lifting up one of the balls for loading.
The link below is just one of the better articles on this weapon (and is also nice and short)
