prohibited area
Off-limits territory
A prohibited area is a zone where entry or certain activities are forbidden, typically by law or official regulation.
The term appears most often in aviation and military contexts, designating airspace or land where unauthorized access is banned for security reasons: The pilot was warned away from the prohibited area surrounding the capital.
More broadly, any space declared off-limits qualifies.
