Ciampino was the first airport serving the Rome area, and though it was replaced for many routes by the larger, newer Fiumicino International Airport, Ciampino remains in operation for many of the domestic and shorter routes within Europe. It is also known as G. B. Pastine International Airport, and services commercial and civilian as well as military aircraft.
The airport opened in 1916 and remains one of the oldest airports still in operation. During World War II, Ciampino was captured by Allied Forces and became a cargo hub, even serving as a United States Army Air Force airfield at one time. Today it welcomes just over 5 million passengers per year and is a hub for Ryanair, the budget airline connecting most of Europe.
