Gibraltar is a British territory located just south of Spain and is less than three square miles. The Gibraltar Airport is the closest airport to a city center (only about 1/3 of a mile) in the world and only five airlines currently serve the airport.
What probably makes it most unique is having the main road connecting Gibraltar to Spain, Winston Churchill Avenue, go right over the runways. Every time a plane takes off or lands, traffic must be stopped.
The airport is in the middle of being renovated. Not only will they be increasing the terminal three fold, they are also constructing a tunnel for vehicle and pedestrian traffic. Although this will make the city and airport run more efficiently, it the airport will lost a little of its unique character.
