The feature titled \u2018The mystery of Cape Town\u2019s disappearing gun\u2019 can be viewed here. According to the respected online newspaper The South African (https:\/\/www.thesouthafrican.com\/), the gallery - produced by former South African journalists, Piet van Niekerk and Werner Hoffmann, working with Content Cows multi-media producers in the UK - tells the story or a rare military relic that was buried for almost 100 years and discovered below the swimming pool of a derelict bed-and-breakfast lodge in Battery Estate in Sea Point. The South African quotes Cape Town archaeology and heritage specialist Tim Hart, who says disappearing guns were extremely unique because it had the ability to \u201chide from enemy fire by lowering themselves into a gun pit\u201d. These guns were fitted with hydraulic lifting mechanisms for the artillery crew to lift the barrel from its loading position under a protective shield into a firing position and rotate it towards the target. After it fired, it would disappear back into a vault under a protective shield. These were extremely rare military mechanisms and great examples of mid-Victorian engineering. Hart said the massive disappearing cannon with its carriage weighed several tons but it\u2019s existence simply disappeared from memory after the property in Sea Point, where it was stationed, was sold off in the 1920s. In early 2018, Hart was called to a building site where a construction worker had been demolishing the swimming pool at an old bed and breakfast with a digger. He discovered pieces of iron, armour plating and a large circular gun pit made of concrete. Hart new immediately that what they found was a uniquely British feat of military engineering. Hart\u2019s research also found that there were very few of these cannon-sized \u2018guns\u2019 used worldwide. According to documents found in the Western Cape Archives and Records Service, at least three disappearing guns were brought to the Cape from England. The New South Wales State Heritage Register mentions 10 of these mountings deployed in Australia, but according to Hart, almost all of these have been demolished. Only parts of one disappearing gun from Cape Town\u2019s Fort Wynyard military base are known to still exist. The rest, as Hart explained, simply vanished. He said disappearing guns were brought to the Cape during a short-lived and \u201cpretty obscure historical event in 1885.\u201d At the time, Hart explained, Britain ruled India, Russia occupied territory in Afghanistan nearby and both countries were worried that the other wanted to extend its control throughout Central Asia. This tension briefly brought Britain and Russia to the brink of war, and Britain feared Russian aggression in India would threaten all of its colonies \u2013 including South Africa. When the British military heard that Russia might send warships to South Africa, the British installed modern breech-loading cannons around the Cape, including three huge and mysterious \u2018disappearing guns\u2019. The site, known as Alpha 1, is considered unique, reported The South African. Because of the rarity of disappearing guns worldwide and the good state of the site\u2019s preservation, Alpha 1 is recognised as a Grade 2 national heritage site, meaning it enriches the understanding of South Africa\u2019s cultural, historical, social and scientific development. The property\u2019s developers have agreed to preserve Alpha 1 in its original location as a museum available to the public. Plans for the museum, which developers hope to open in early 2020, include suspending parts of the gun\u2019s original blast shield from the ceiling.
