The Echo of the Hamilton Mausoleum
Close the door of this Scottish tomb and the echo hangs in the air for around 15 seconds.
What was reported
The Hamilton Mausoleum was built in the mid-1800s for Alexander, 10th Duke of Hamilton, as a grand tomb and chapel crowned by a stone dome. The chapel was never usable for services, because the echo was too long for speech to be understood.
When the heavy door is closed, its echo lingers for about 15 seconds. For years it was said to have the longest echo of any man-made structure.
Explanations offered
Its hard stone surfaces and the shape of the dome reflect sound around the space again and again, losing very little. In 2014 a disused fuel tank at Inchindown, also in Scotland, took the record, but the mausoleum remains a famous place to hear a single note linger.
