Lift C9/M9 Llanberis bomb stores. - a photo on Flickriver

Glynrhonwy Isaf slate quarries were aquired by the Air Ministery in 1939 and opened as a bomb storage depot during 1941. The stores were in use until 1956, however, this was not without a major construction mishap, shortly after opening

"In response to pressure from the treasury efforts were made to cheapen and accelerate the construction of Llanberis, but unfortunately the cost cutting had disastrous consequences only six months after the depot was opened.

On 25th January 1942, two-thirds of the structure collapsed within seconds under the weight of the overlaying backfill, completely engulfing a train of twenty seven wagons which was in the process of unloading. The collapse buried over 14,000 tons of bombs which at the time represented 14% of the total RAF stock. A court of inquiry concluded that faulty design was the principal cause of the failure; cracks were noticed in the structure as the building neared completion but these were attributed to minor defects rather than to a major and fatal miscalculation."
