Edo was repeatedly devastated by fires, the Great Fire of Meireki in 1657 being the most disastrous, with an estimated 100,000 victims and a vast portion of the city completely burnt. The population of Edo was around 300,000, and the impact of the fire was tremendous. The fire destroyed the central keep of Edo Castle, which was never rebuilt, and it influenced the urban planning afterwards to make the city more resilient, with many empty areas to break spreading fires, and wider streets. Reconstruction efforts expanded the city east of the Sumida River, and some daimyō residences were relocated to give more space to the city, especially in the immediate vicinity of the shogun's residence, creating a large green space beside the castle, now the Fukiage gardens of the Imperial Palace. During the Edo period, there were about 100 major fires, mostly begun by accident and often quickly escalating and spreading through neighborhoods of wooden nagaya that were heated with charcoal fires.
