The record — long form

The Castillo de San Marcos was built from 1672 to 1695 — the Spanish coquina fort at St. Augustine, the oldest masonry fort in the continental United States, never taken by force in three centuries of sieges.

The file's documented spine is the fort's invincibility: a fortress that absorbed every attack, its walls of compressed shell being the defense that never failed — the Castillo being the record's proof that some ground is unassailable.

The Castillo dead

The Castillo dead are the file's signature — a fort that was never taken keeping its defenders, the coquina walls reportedly still patrolled by the men who never lost them.

Why this file matters

The Castillo is the archive's unconquered file — the country's oldest masonry fort, never taken, keeping its dead reportedly on the walls. The documented invincibility is the record; the lingering garrison is the lore of a fort that never fell.

A fort that never fell keeps its defenders — the file's suggestion being that the Castillo's watch is still being kept by the men who made it impregnable.
