The Indonesians noticed this too -- they call it Benteng Penyu, the sea-turtle fort -- and the resemblance is no accident of erosion or urban encroachment. Dutch military engineers gave it that shape deliberately in the 1670s, when they rebuilt a conquered Makassarese fortress into the centerpiece of colonial power on Sulawesi. The turtle has outlasted every regime that occupied it. Four centuries after the first walls went up, the fort sits in the heart of modern Makassar, its seven-meter ramparts enclosing museums, a music conservatory, and the ghosts of a Javanese prince who spent the last 25 years of his life imprisoned within its bastions.
