The Patronato gives 28 hectares for Panamá Viejo’s archaeological area and 60 hectares for the original city. The Panama Canal Authority reports that basins in the expanded locks return 60% of water from each ship passage for reuse.
At a glance
A place worth remembering
The archaeological area at Panamá Viejo
On its Panamá Viejo page, the Patronato gives separate figures for the archaeological area (28 hectares) and the original city (60 hectares).[1]
How the expanded locks reuse water
In its 2016 expansion account, the Panama Canal Authority says the new locks’ basins make 60% of water from each ship passage available for reuse.[2]
Founded in 1519, moved after the 1671 attack
The Patronato says Pedrarias Dávila founded Panama City at this site on 15 August 1519. After Henry Morgan’s attack in 1671 left the city in ruins, it was moved two years later to what is now called Casco Antiguo. The Patronato says the old site then stayed abandoned for more than two centuries, which allowed valuable remains of the colonial and pre-Hispanic past to survive.[1]
Good to know
A few clear answers before you explore.
Does the 60% figure describe all the water in the Canal?
No. The ACP applies it to water used during one ship passage through the expanded locks; the figure describes reuse by that lock system.[2]
What does each Panamá Viejo area figure describe?
The Patronato gives 28 hectares for the archaeological area and 60 for the original city’s extent.[1]
Is Panamá Viejo the same place as Casco Antiguo?
No. According to the Patronato, the city was founded at Panamá Viejo in 1519; two years after the 1671 attack it was moved to what is now called Casco Antiguo, and the old site was left abandoned for more than two centuries.[1]
