The 20th century historian of Paris René Héron de Villefosse shared the same view of Haussmann's renovation: "in less than twenty years, Paris lost its ancestral appearance, its character which passed from generation to generation... the picturesque and charming ambiance which our fathers had passed onto us was demolished, often without good reason." Héron de Villefosse denounced Haussmann's central market, Les Halles, as "a hideous eruption" of cast iron. Describing Haussmann's renovation of the Île de la Cité, he wrote: "the old ship of Paris was torpedoed by Baron Haussmann and sunk during his reign. It was perhaps the greatest crime of the megalomaniac prefect and also his biggest mistake...His work caused more damage than a hundred bombings. It was in part necessary, and one should give him credit for his self-confidence, but he was certainly lacking culture and good taste...In the United States, it would be wonderful, but in our capital, which he covered with barriers, scaffolds, gravel, and dust for twenty years, he committed crimes, errors, and showed bad taste."
