The Quenast quarry (French: Carrière de Quenast) or Porphyry quarries of Quenast is a historic porphyry deposit in Belgium and Europe's largest open-pit quarry. Porphyry has been mined from the quarry as an important source for construction since the 17th century and was traditionally used to make Belgian cobblestones for city streets.[1]
