Penzance, town (parish), Cornwall unitary authority, southwestern England. It overlooks Mount’s Bay, where the English Channel meets the Atlantic Ocean.
The area’s remarkably equable climate allows many subtropical plants to flourish. Early vegetables and flowers are raised locally and on the offshore Isles of Scilly, with which Penzance is linked by sea and air services. Newlyn, nearby, is a small fishing port much frequented by artists. The occasional pirate raids Penzance experienced during the 17th century, because of its location on a sheltered bay at England’s southwest tip, made it the location for the Gilbert and Sullivan operetta The Pirates of Penzance. The chief modern functions of Penzance are as a tourist base for the region and as a local service centre. Pop. (2001) 21,168; (2011) 21,045.
