Tyneham in Dorset was a village - until it was handed over (by compulsory purchase order) to the War Office during WW2 to be incorporated into the nearby live firing range for troop firing. Still in the middle of a live firing range, but now opened to the public on a few days each year.
The majority of the residents didnt own their houses so got little more than the value of the vegetables growing in their gardens with their 1 months notice to move out. Although originally promised they would be allowed back, this was reversed in 1948 when it proved a useful training ground.
Now it is an eerie place, forever stuck in the past. Most of the buildings have had their roofs removed to make them safe.
