477 wasn't that bad. Ravenna was capital, but Rome itself was kept in decent shape. The forum continued to be swept. The aqueducts kept working. Still, at the time, the population was declining and civic upkeep became harder and harder. The Senate still met. There are stories of thieves stealing whole statues while poorly paid watchmen slept or we're bribed not to notice. It reminds me a bit of Detroit. Still, the structure of the city was fairly well preserved. It wasn't until the Gothic Wars in a few decades until Rome was utterly wrecked and depopulated. The city changed hands five or six times, and armies frequently cut the aqueducts, never to be repaired. The last recorded act of the Senate was in 603. Then, around 900, a few earthquakes caused the final collapse of long neglected buildings. Nobody cared to fix them, but they did use the rubble for other construction over the next few hundred years. (Not that there was that much new construction: Rome's population crashed from over a million to 30,000.)
