The Panama Canal is an artificial 82-kilometre (51-mile) waterway in Panama that connects the Atlantic Ocean with the Pacific Ocean, cutting across the Isthmus of Panama, and is a conduit for maritime trade. Locks at each end lift ships up to Gatun Lake, an artificial fresh water lake 26 meters (85 ft) above sea level, created by damming up the Chagres River and Lake Alajuela to reduce the amount of excavation work required for the canal. Locks then lower the ships at the other end. An average of 200,000,000 L (52,000,000 US gal) of fresh water is used in a single passing of a ship. The canal is threatened by low water levels during droughts.

The US's intentions to influence the area (especially the Panama Canal construction and control) led to the separation of Panama from Colombia in 1903.
The Panama Canal Zone, also simply known as the Canal Zone, was a concession of the United States located in the Isthmus of Panama that existed from 1903 to 1979. It consisted of the Panama Canal and an area generally extending five miles (8 km) on each side of the centerline, but excluding Panama City and Colón. Its capital was Balboa.

Gorgas Hospital was built by the French as L'Hospital Notre Dame de Canal in 1882, renamed Ancon Hospital when the U.S. assumed control in 1904, rebuilt in 1915 and finally renamed in honor of William C. Gorgas in 1928. It is now home to Panama's Ministry of Health and the Instituto Oncologico Nacional.
