Czerniaków area according to City Information System in Warsaw
Called Czerniakowo since the Middle Ages, it was then merely a small village located well to the south of the Warsaw's Old Town. In the 19th century the area became densely built-up and became populated mostly by factory workers and other lower classes of society, which gave birth to a specific local version of the Warsaw dialect. During the Warsaw Uprising the area was one of the last Polish strongholds.
