The soaring Gothic tower of Saint-Germain-l'Auxerrois — the ancient royal parish church whose bell once signaled the St. Bartholomew's Day Massacre in 1572 — dominates this crisp early photographic card, its intricate stone tracery rendered in deep, velvety halftone tones. The church stands just east of the Louvre, and the open square in front is busy with horse-drawn vehicles and pedestrians barely caught by the slow emulsion of the era. The adjacent neo-Gothic mairie of the 1st arrondissement peeks in from the left, the rose window of its facade a mirror to the church's own. Publisher mark "E. R. Paris" is visible vertically along the left edge — a small but collectible imprint associated with early Paris topographic cards. The undivided back (image _02) places this firmly before France's 1904 divided-back regulation, making it a genuine turn-of-century document of one of Paris's oldest and most storied churches.
