In 1657, the city of Edo was razed by a great fire, known after the year period as the "Meireki Fire." It was a decisive turning point in official attitudes towards large-scale building, which was now discouraged in favor of simple maintenance and a much less sumptuous style. The great donjon of Edo Castle itself, for example, was never rebuilt, giving this greatest of Japanese castles a much more subdued appearance. So also the ornate style in which many of the daimyo mansions of Edo were built was prohibited. Thus came to an end the "Golden Age" of classical Japanese architecture.
