Inundation, Gibraltar, Military fortification site in Gibraltar, United Kingdom.
The Inundation formed a water-filled defensive barrier on the isthmus connecting Gibraltar to Spain, stretching 200 yards in length and 60 yards in width.
British military engineers transformed a natural marshland into an artificial lake with defensive structures in 1735, establishing a controlled water barrier between Gibraltar and Spain.
Local soldiers stationed at the fortification nicknamed the water feature Lake Chad during World War II, reflecting their experience of this military infrastructure.
The Inundation contained underwater stakes and iron barriers designed to prevent unauthorized access, with a narrow causeway serving as the only passage point.
Fish populations thrived in the waters of the Inundation by 1840, creating an unexpected natural aquarium that only military personnel could observe.
