What is the story behind Castillo San Felipe de Barajas?

Perched on the Hill of San Lázaro overlooking Cartagena, Castillo San Felipe de Barajas is the largest and most complex fortification built by Spain in its American colonies. Construction began in 1536 and expanded dramatically over the next two centuries, creating a layered system of batteries, tunnels, and traps designed so that if any section fell, the defenders could retreat and destroy the captured area. The fortress famously repelled the 1741 siege by British Admiral Edward Vernon, who attacked with 186 ships and 27,000 men — one of the largest amphibious assaults before D-Day — and lost.
