Lighthouses tend to not snap and fall over, the lighthouse at Nygrån didn't get the message - 1969 - Gulf of Bothnia (lemmy.zip)

This is an interesting one, this is caisson lighthouse built between 1957-1958, it was shipped out and installed in 1958.

During the winter of 1969, eleven years later, the lighthouse was shorn off it's foundation by the pressure of the ice around it, this caused it to fall over.

The lighthouse fell over (not very typical), and electric light went out, but the backup gas powered Dalén light turned on and worked!

Here is a diagram of the lighthouse showing the shear point, with helpful text in english:

A new lighthouse was built and installed in 1970.

The picture is as far as I can tell licensed as CC-SA-BY, but I can't find any photographer information, the only ownership information I can find is that it belong to an archive maintained by a person called "G Kjellgren"
