And yet, for at least a thousand years, people have been drawn to this barren, wind-scoured rock off the coast of Callao. The ancient Peruvians carried their dead across the channel called El Boqueron and buried them here, because in the mythology of the central coast, offshore islands belonged to the afterlife. Pirates anchored in its lee to raid the mainland. Charles Darwin walked its slopes and studied its geology. Dictators locked their enemies in its naval base. At 16.48 square kilometers, San Lorenzo is the largest island in Peru -- and one of the most storied places no one has ever called home.
