Spanish forces under Pedro de Cevallos captured the half-built fortress by capitulation on April 19, 1763, taking the Portuguese commander Tomás Luis de Osorio and a hundred-odd defenders along with the unfinished walls. The fort changed hands almost before it was a fort at all. That single exchange tells you everything about Santa Teresa: this pentagon of granite was never a peaceful place but a contested key, set down at the exact point where two empires pressed against each other on the edge of South America.

It served briefly as a watchtower during the civil wars of the 1830s and 1840s, then as a prison in 1895, and finally as little more than a shelter fo...
