VIDEO: Some of the world's biggest sinkholes...and Swansea's dip
IN honour of the sinkhole that isn't - in Pier Street, Swansea - we have brought you some footage of some genuinely scary voids.
You can see them further down in this article.
But as far as the Pier Street hole is concerned, one resident said: "It started out quite small, and people would put leaves and other stuff from gardening in the hole to fill it.
"But it just keeps appearing, and it's been getting bigger.
"There is now quite a dip in the grass, and we don't know how deep it goes down.
"We don't know if it is a sinkhole"
The hole is approximately six foot in diameter, and has been fenced off by Gwalia, as they attempt to find out the reason for its appearance.
But Gwalia has confirmed it is not a sinkhole.
