We trace two very different ways of moving wealth across this isthmus, three centuries apart.
A bus first takes us to Portobelo, once the Caribbean terminus for Spain's entire Pacific trade. An annual fair here ran thirty to sixty days, moving ten to twelve million gold pesos at a stretch, before pirate raids grew persistent enough that Spain abandoned the route in 1738.
Fort San Geronimo and Fort Santiago still stand guard over a harbour long since gone quiet, though it once anchored more treasure than any other port in the Spanish Americas. Inside San Felipe Church, the Black Christ, a life-sized wooden Jesus found on the shore under circumstances nobody fully agrees on, draws pilgrims from across Central America each October.
NOTE: some monuments may be inaccessible due to ongoing renovations.
From Portobelo we continue to Agua Clara Locks, part of the canal's modern expansion, where overflow tanks recycle 60 per cent of the fresh water each transit uses, gravity doing now what it did for Spanish galleons then, just with better bookkeeping.
We finish the day boarding the Interoceanic Train at Colon for the run back to the capital. Completed in 1855, it was the world's first transcontinental railway, just 80 km/50 mi long, and it carried Gold Rush prospectors long before it carried canal freight.
Overnight in Panama City.
