On Saturday, John Dereszewski is giving a walking tour of Bushwick Avenue in Williamsburg. Bushwick & Metropolitan is pretty much ground zero for the origins of European settlement in North Brooklyn. Through some twist of historical fate, when Williamsburg was made an independent town from Bushwick, the original Bushwick settlement was included in Williamsburg. Its that part of Bushwick Avenue – from Woodpoint Avenue to Flushing Avenue – that Dereszewski will be discussing.
