Hamilton, Italy
The Hamilton Mausoleum is a mausoleum located in Hamilton, South Lanarkshire, Scotland. It was the resting place of the family of the Dukes of Hamilton. The mausoleum is Category A listed. Built in the grounds of the now-demolished Hamilton Palace, its high stone vault holds the record for the longe
st echo within any man-made structure in the world, taking 15 seconds for the sound of a slammed door to fade. In 2014 the record was thought to have been broken at the Inchindown oil storage tanks in the Scottish Highlands, however this was classed as a reverberation, rather than an echo.
