Caithness
From Tardis Wiki, the free Doctor Who reference
Caithness was a location in Scotland.
A town called Краснодар was located there. The town, built sometime before 1980, was used to train soldiers during the Cold War. It was flooded in 1980, (TV: Before the Flood) and was later the location where the Drum was built in the early 22nd century. (TV: Under the Lake)
