One January night in 1974, the Berwyn Mountains shook as a brilliant light was reported across the sky — the event that made Denbighshire famous, set within a longer local record of lights.
Denbighshire, in north-east Wales, is best known for the Berwyn Mountain event of 23 January 1974 — an official-record case explained as an earthquake and a meteor. But the county’s record of reported lights runs before and after that night.
On the evening of 23 January 1974, residents around Llandrillo reported a loud noise and a bright light over the Berwyn Mountains. Within days the event had drawn police attention and, later, a claim that a craft had come down — an episode the press nicknamed the “Welsh Roswell”.
The Berwyn event has its own deep case study. This Regional File treats it as the county’s strongest institutional anchor — the detail lives in the flagship file.
In October 1978, according to the SUFON record, three police officers in the grounds of a hospital at Denbigh reported seeing a UFO. The independent press account has not yet been recovered, but the report sits within a county whose record includes several other unusual nights.
A few reports stand out across the county’s history — a 1964 report of a beam of light that burned a woman and her dog at Denbigh; a pair of gold bars reported over Rhyl on two October 1986 nights; and a 2011 Llangollen report of a white light that became a “winged pod”. The full record follows below.
