Criggion VLF Transmitter

A towering lattice mast rising from the Powys countryside near Llandrinio - that's your first clue that Criggion VLF Transmitter is something properly unusual. This isn't a country house or ancient monument. It's a working Very Low Frequency transmitter, the sort of Cold War-era installation that most people drive past without a second glance.

The site itself is fascinating if you're into industrial heritage or military history. The transmitter was built to communicate with submarines - VLF signals travel through seawater where radio won't reach, which made this place strategically crucial during decades of tension. The mast dominates the landscape in a way that feels almost eerie, and the technical infrastructure around it tells a story of mid-20th century engineering ambition.

Access and visiting details are sketchy - there's no formal visitor infrastructure that I'm aware of, so check locally in Llandrinio before planning a trip. This isn't a destination where you'll spend two hours; it's more of a worthwhile detour if you're already exploring the Powys hills. History enthusiasts and anyone interested in Cold War sites will find it compelling. Families with kids aged ten and up might enjoy the oddness of it, though younger children won't get much from standing outside a fenced industrial site.

It works brilliantly as a curiosity stop during a caravan holiday - Bank Farm or Grantley Court are both within two miles - giving you something genuinely different from the usual countryside attractions. Frankly, the rarity of it is the appeal.
