The Sablon or Zavel is a neighbourhood and hill in the historic upper town of Brussels, Belgium. At its heart are twin squares: the larger Grand Sablon (French) or Grote Zavel square in the north-west and the smaller Petit Sablon (French) or Kleine Zavel square and garden in the south-east, divided by the Church of Our Lady of Victories at the Sablon and the Rue de la Régence/Regentschapstraat.
