Among all the engineering feats of the 20th century, the Panama Canal was certainly one of the greatest. The Panama Canal Authority (PCA) provides this home page, which contains a vast amount of information regarding the canal's origins and current affairs. Most visitors to the Web site will be mainly interested in the complete history of the canal. This begins with early plans by the Spanish in the 1500s, and documents all progress until the final completion in 1914. An impressive photo gallery includes historical pictures and panoramic views of four main locations, and a live camera shows the boat traffic in the canal at ten second intervals. Other resources such as maritime operations and news articles are also available.
