De Valera’s former safe house (and cabinet nuclear bunker site) in Co Kildare for €1.6m Victorian manor on seven acres in Clane has cold war bunker among its many curiosities

"According to the current owners, but the department of defence made the basement into a bunker, which was to be used by senior government officials in the event of a nuclear war."

For there to be more visits to underground sites, there needs to be more people organising them.

If you know the history of an underground place that should be, but isn't on our website www.subbrit.org.uk, please send text, and ideally pictures (your own not copied) to webupdates@subbrit.org.uk, citing sources whenever possible.

I went on a hunt for the new Piccadilly Line tube trains yesterday.

I'd seen that they were testing them around Acton Town on Saturday, so headed over there to see if I could see one, and I struck the jackpot! There was one waiting in a siding, then another came round the corner into the platform!

I caught up with it at Hammersmith, saw two units out on test trundling up and down the line. Official TfL line is that the trains will enter service in the second half of 2026.

AI generated spoof movie poster entitled Tunstall Has Fallen featuring Gerard Butler in ROC uniform (with incorrect badge) and the tettering cliff top building.

Sea erosion has caused the Royal Observer Corp post at Tunstall to fall down on the beach.
It's been the biggest cliffhanger since a sister post at Aldborough met a similar fate.
