There are abandoned sites that have fascinating features. One of the most amazing is found in the Scottish Highlands.<\/p>\n

In 1938, the British Royal Navy began construction of a large ship fuel depot<\/strong> at Invergordon, near the city's naval base. Officially named Inchindown Royal Navy Fuel Tanks, the bomb-proof, underground tank was completed in 1941<\/strong> and consists of six tanks, five of which are 237 meters long, 9 meters wide and 13.5 meters high, and a sixth shorter tank.<\/p>\n

The tank remained in service until the Falklands War (1982), when it reached its maximum capacity, according to BBC<\/a>. In 1988 a plan to upgrade this reservoir was scrapped and it was finally abandoned in 2002<\/strong>, after undergoing extensive cleaning. Outwardly, the deposit goes very unnoticed. The only clue that there is a huge deposit there are the accesses to it.<\/p>\n

In January 2014, this ancient repository was the site of a curious test<\/strong> organized by Professor Trevor Cox, an acoustic engineer at the University of Salford, and by the Royal Commission on the Ancient and Historical Monuments of Scotland (RCAHMS): a gun was fired inside the tunnel and the reverberation of the sound lasted 112 seconds, setting a world record<\/strong> that until then had been held by the Hamilton Mausoleum in Lanarkshire since 1970.<\/p>\n

In 2018, Tom Scott repeated that test <\/strong>, which we can see in this video:<\/p>\n
