2Gibraltar International Airport, Gibraltar
Gibraltar International Airport is one of the most unusual airports in Europe, largely because of its extraordinary location between the Mediterranean Sea and the Atlantic Ocean.
The airport sits close to the famous Rock of Gibraltar, which creates particular considerations for approaching aircraft. Winds can be affected by the surrounding geography, while the restricted urban environment leaves limited room for airport expansion.
Another unusual feature is that a major road historically crossed the runway, requiring traffic to stop whenever aircraft were landing or taking off. A road tunnel subsequently provided an alternative route.
Although its runway is considerably longer than those at some extreme mountain airports, Gibraltar remains an interesting example of how geography and urban development can complicate airport operations.
