The Fuerte de San Diego and the Manila Galleon Trade

Star-shaped fortress on a hill above the harbor. Built 1616, destroyed by earthquake 1776, rebuilt by 1783. Now houses the Museo Historico de Acapulco. Stepping inside the pentagonal walls is stepping into the centuries when Acapulco was one of the most important ports in the world.

The museum tells the Manila Galleon story — the 250-year trade route connecting Acapulco and Manila, sending Mexican silver east, returning with Chinese silk, porcelain, spices, ivory. The world's first global trade route. The galleries have navigational instruments, trade goods, and galleon models — ships of 1,500 to 2,000 tons making a Pacific crossing that took four to six months and killed men routinely through scurvy, storms, and the sheer cost of living on wood in the tropics for half a year.

The Asian trade goods collection is remarkable — porcelain from Jingdezhen that traveled to Manila to Acapulco to Mexico City, 15,000 miles of ocean in a ship's hold. A 1730 cargo manifest lists silk, beeswax, cinnamon, and "curiosities." The global economy in embryo.

In the lower gallery, a stone drain in the floor of a holding cell — carved so the floor wouldn't flood during monsoons. Cruelty and consideration in the same stone walls. Tuesday through Sunday, nine to six.
